Unable to send or receive messages for an email account. Errors sending and eliminating them to send a test e-mail
When you, being out of the house, send a message. email using homemade postal accountThis message may return with an 550, 553 error or relay error. The same can happen when you, being out of office, are trying to send an email with a working postage account.
Description
Research occurs when the mail message is sent to the email address, the domain of which (name after the @ symbol, for example, adatum.com) is not processed by the SMTP protocol or the outgoing mail server receiving a message delivery request from the sender. The SMTP server must be connected to another SMTP server to relay the message.
If you send a retransmission error when sending a mail message, your SMTP server (outgoing mail) can return your message along with an error message, for example, of this type:
"Unable to send a message, since the server refused to make the address of one of the recipients. The letter was specified in the letter:<адрес эл. почты>. Subject:<тест>, Account:<тест>, Server:
The exact text of the error message will depend on your Internet service provider. Some providers do not return an error message when the outgoing messages are determined as unwanted advertising. In these cases, everything looks like your message is sent to as usual mode (in Outlook remains in the folder Outgoing and appears in the folder Posted), but it is not delivered to the recipient.
Your message is rejected because the SMTP server (outgoing mail) did not recognize you as a powerful user.
SMTP is a protocol (standards used by computers for interaction), which is used on most email servers to send messages on the Internet. If you are using a mail program (for example, Outlook), which allows you to store messages on your computer, you need access to the SMTP server to send messages.
Note: Email web systems (for example, Windows Live. Mail or Yahoo! Mail) work otherwise and are not considered in this article.
Unwanted mail and open relay
Advertising messages distributed without request are called unwanted mail or spam. The volume of unwanted mail continues to grow, because its sending is practically nothing worthwhile who sends it. In fact, the sender does not even necessarily send unwanted mail via the SMTP server (outgoing mail) of its Internet service provider.
When creating the basic structure of the Internet, no one foresaw, which consequences will be able to send millions of unwanted messages for a negligible fee. Thanks to the ability of SMTP servers to relay, the senders of unwanted mail mask its authentic source, passing it through third-party servers on which such open relayings are allowed. As a result, the unwanted mail seems to come from the site that relays the message and hides the identity of this sender.
Until recently, most mail SMTP servers worked on the basis of confidence open system. In such a system, anyone else can send a mail message to the SMTP server, and the server must accept it and send it to the recipient or another postal server on which is located mailbox Recipient. With such an open retransmission there are no restrictions prohibiting anyone to send mail via the SMTP server.
Internet service provider restrictions on email relay
As the unwanted mail increases, the network administrators (people responsible for managing Internet service provider servers have begun to enter restrictions on their postal SMTP servers. These restrictions do not allow the use of the mail server to all in a row. Imagine that in the lobby of your organization there is a telephone available to all, including those who are not an employee of the organization. Now the phone is allowed to use only employees.
To date, the limitations of several types are used.
SMTP authentication is required. Just as you use the username and password to access the POP3 server (incoming mail) and your email messages, you need to enter the username and password to send mail messages via the SMTP server. Usually it is the same username and password as for the POP3 server, but may be unique.
You need to first connect to the POP3 server (incoming mail) of the Internet service provider. To get your new mail messages, you usually be connected to the POP3 server (incoming mail). To access the mailbox, you need to enter the username and password. The network administrator can configure the server in such a way that if you first connect to the POP3-server of incoming mail and pass the authentication, it will approve all requests for sending mail messages via an outgoing mail SMTP server, wherein other cases will be limited.
A connection is required from an authorized location on the network. If you are connected to the Internet service provider, using a cable or through a DSL modem, the connection goes directly to the provider's network. You deserve confidence because you have an account with the username and password that provided the Internet service provider. You like the client is allowed to use the SMTP server to send mail messages.
A connection is required from a specific IP address or IP address range. Your Internet service provider can allow access to the SMTP server to people who are not directly connected to the network. For example, it can be a remote user in the office. The main problem is that in many places dynamic IP addresses are used. At the same time, you cannot be sure that each time you connect the same IP address. In some organizations, a block or range of IP addresses can be reserved. Internet service provider may consider those who are connected to these IP addresses, proven users. It can provide additional information.
Possible relay scenarios are a lot. Below are the most common situations. Perhaps one of them looks like yours.
Situation | Is it a relay? |
|---|---|
|
You are at home, and you have an Internet service provider account, ending with @ ProSeware.com, from which you connect via the telephone line using a cable or via a DSL modem. You send a message to another person, whose postal address also ends with @ pro seware.com. |
|
|
The same as in the first situation, only you send a message to a person, whose mailing address ends on @ adatum.com. |
Yes, but it is not blocked. You are connected directly to the Internet service provider and thereby get powers to send mail through its SMTP server (outgoing mail) to any addresses, regardless of the location of the recipient's mailbox. |
|
Are you at work. Your work postal address ends on @ thephone-company.com, and you have a home account of the Internet service provider, the address of which ends on @ pro seware.com and from which you connect via a telephone line using a cable or through a DSL modem . In Outlook, you have the same SMTP server settings as home. You send a message to a person, the mailing address of which also ends on @ pro seware.com. |
Not. Your mail is processed in the usual way. |
|
You stayed at the hotel or took advantage of the airport of the Internet terminal providing internet access. You have a home account of the Internet service provider, ending on @ ProSeware.com with which you connect through a telephone line using a cable or via a DSL modem. In Outlook, you have the same SMTP server settings as home. You send a message to another person, whose postal address also ends with @ pro seware.com. |
Not. Your mail is processed in the usual way. |
|
The same as in the previous situation, only you send a message to a person, whose mailing address ends on @ adatum.com. |
Yes, and this message can be blocked as a relayed mail. You are trying to use your home SMTP server (outgoing mail) of your Internet service provider, although not connected to its network. The SMTP server cannot verify you as an Internet service provider's authorized subscriber. In addition, you ask the SMTP server to accept the message and connect to another SMTP server to deliver it to the recipient's mailbox. |
Solutions
If your situation is seen as relay, you must send a message through the server to which you are now connected. That is, if you are at work or outside the house and do not use your Internet service provider to connect to the Internet, but you want to send a message from your home account provided by this provider, you need to change the mail account settings, specifying that SMTP server which you use where you are (for example, a working SMTP server). Step by step instructions See the article.
If it does not work or you prefer to use a home account, you need to contact your Internet service provider and ask whether you have previously described parameters. As for the first two restrictions (SMTP authentication is required and you must first connect to the POP3-server of incoming mail Internet service provider), you can make changes to Account Settings in Outlook. For instructions, see the article Changing Email Account Settings.
Are the messages still not sent?
You changed the SMTP settings in Outlook or found a parameter that will allow you to send mail messages. But you still can't send mail and get an error message.
You may have done everything right, but network administrators use some other security system function to prevent identity spanning. The set of certificates is just a way to send a mail message at which you hide who you are.
In Outlook, as in most postal programs, You can specify the "display name" and the return postage address that appears when answering your message. In the unwanted mail, these fields almost always contain false information. Do you really believe that reports are about how to get rich quickly, came from supermodel or world leader?
To prevent identity spoofing, some Internet service providers restrict the possibility of inserting false information in the address field in the responses. For example, if domain name Your Internet service provider ends on ProSeware.com, the provider may prohibit you specify the return address [Email Protected] . This restriction is not used as widely as described earlier, but can be applied to all users regardless of their location and method of connection. In this case, there is no alternative. If the server administrator uses this method, you must specify a domain in the opposite address that matches your current connection.
Decision: Connect the computer to the Internet or to the network.
Open the web browser to see if there is access to the Internet sites. If you are in local networkCheck if you can open the intranet sites. Information about how to check the condition network connectionsSee in Mac OS Help.
Decision: Make sure Outlook is connected to the Internet.
On the menu Outlook. Look, if the checkbox is installed Autonomous work.
Cause: Some POP and IMAP email accounts use outgoing mail server (SMTP) for which authentication is required.
Decision: Enable SMTP authentication for POP or IMAP account.
Some email services, including ICLOUD email accounts, require authentication for their SMTP server. If you make sure that all account settings are set correctly, but you still cannot send messages, try disable SMTP authentication.
On the menu Service Choose accounts.
Accounts Select an account.
In chapter SMTP server. Choose Extra options ...
In the pop-up menu Authentication Select the authentication type and enter the necessary credentials.
Cause: The Internet service provider or network administrator uses a firewall that blocks the connection to the Outbound Mail Server (SMTP) of your email service.
Decision: Find out if your Internet service provider or network administrator provide an alternative SMTP server for your POP or IMAP account.
If there is an alternate SMTP server address, specify it in the account settings.
On the menu Service Choose accounts.
In the left area of \u200b\u200bthe dialog box Accounts Select an account.
In field outgoing mail server Enter the name or server address.
Note: When using a laptop in several locations, such as at home and at work, the SMTP server that is used in one place may not work in other places. Each to the Internet, with which you, possibly, firewall with restrictions own.
Cause: Account or Account Settings are incorrect.
Decision: Check if your username, password and other account settings are correctly listed.
On the menu Service Choose accounts.
In the left area of \u200b\u200bthe dialog box Accounts Select an account.
Make sure you entered the correct email address, username and password.
If the account still works incorrectly, contact your email service provider to find out how to configure your account in mail application. You may need to use special parameters for your account, for example, apply sSL protocol To connect or override the default port.
Cause: Networks require a proxy server to connect to the post server.
Decision: Specify the mail proxy server in the section " System settings" on the computer.
If you use networks to connect to the Internet, you may need to specify the proxy mail mail. Contact your network administrator for the correct parameters for your post proxy server. Instructions on how to enter these parameters, refer to the Mac OS reference system.
Cause: Email server is not available.
Decision: Check if the mail server works.
If you used to have been successfully connected to this account, perhaps the problem is that the mail server is disabled. Contact your email service provider or network administrator to find out if the mail server works.
If sending errors in the distribution process, you need interrupt Newsletter, go to "Settings / General Settings / SMTP Tab" and edit current settings. Then continue the newsletter: press the black triangle near the "Start" button and select the desired option (to transfer to another or unsuccessful sent).

Good day Dear blog readers Website, today I will tell you how I ran into a mistake when trying to send a message to Microsoft Outlook. 2013, here with such a wording of server response 550 5.7.1 Sender Unnown, the error code was 0x800CCC78, I honestly did not meet it before. It swears that allegedly not the right sender on a computer, a very strange wording, but there are no mysticism, everything turned out to be very trite with the echo of the human factor, wherever without him.
Error 0x800CCC78 Unable to send a message
Little we had a 0x800CCC0F error in MS Outlook 2007, this also flew and this. Here is more clearly what looks like this error. The most interesting thing is that the incoming letters came, and there are no outgoing. Having issuing such a message.
The task is sent to the error 0x800CCC78, it is impossible to send a message. Check email address in account properties. Server Run 550 5.7.1 Sender Unknown
I was a little embarrassed because the incoming mail was. We go into the properties of your account and check, I had a grammatical error in the email address field, apparently my colleague made it. Make sure you have an email address field and the user had one value.
The table below lists error messages that may occur when working with G SUITE email services. These messages help to find and fix the problem with email.
To designate the error source, Gmail adds one or both of the following fragments to the end of the message:
- gSMTP. (Google SMTP): added to everything error messages;
- gCDP. (G Suite Custom Domain Policies): Added to error messages related to the rules that are created by the G Suite administrator.
For example, a message "550 5.7.1 This message violates EXAMPLE.COM to e-mail. - GCDP
