Why Foxmail can't send mail

Foxmail can not normally send mail, generally due to the following problems, please check each:

I. Account configuration

1, the main interface click "Tools"-"account Management", the left to select the account, the right select "Server" to check whether the incoming mail server (SMTP) is filled in correctly.

2, under normal circumstances, "server" page in the middle of the "Send server needs Authentication" is required to check, click "Settings" to confirm ESMTP verify information is set correctly. (Generally choose to use the same information as the IMAP/POP3 server), you need to pay special attention to some servers require the use of the first half of the e-mail address (that is, the e-mail address, the "@" character on the left), but some mail servers need to use the full e-mail address, After the problem is encountered, it is recommended that you replace the attempt in both of these items. )

3. Under the Server page, find advanced, check the port and secure connection settings correctly after clicking.

4, some servers need to be in the "server" page under the "Advanced" check "if the server support, use STARTTLS encrypted transmission", such as vip163 account, Hotmail account (including @hotmail.com, @live. com and @live.cn) and so on.

Second, anti-virus software

Partial anti-virus software's mail monitoring function may cause the Foxmail not to receive the mail normally, please turn off the anti-virus software The mail monitoring function, or temporarily disables the anti-virus software to confirm.

Third, network and proxy settings

1, because of the network reason, cannot connect with the server. Check that your network environment is correct.

2, the main interface click "Tools"-"System Settings"-"Network" Check the Foxmail 7 mail client system proxy settings are correct.

3, the main interface click "Tools"-"account Management", the left to select the account, the right select "Server", in the "server" page below to find "advanced"-"Proxy settings", check whether the account set up an independent agent.

Four, the account number of the SMTP feature is enabled

Please confirm that the account has SMTP features enabled, such as QQ mailbox Pop3/imap function is to be manually enabled (QQ Mailbox Top "Settings"-"Account"-"POP3/IMAP/SMTP service").

Error messages are returned when a message is sent, and can be handled according to specific circumstances. Common error messages are:

1, the server returns "535 error:authentication failed".

There was an error in SMTP authentication. Most mailbox-delivered mail servers now require authentication. In the Mail Server property page of the Foxmail Account Properties dialog box, select the SMTP mail server requires authentication and fill in the correct mailbox account and password under POP3 mailbox account and password. If the SMTP and POP3 servers that are filled out in the account properties are not provided on the same mailbox, click the Setup button to complete the authentication information in the Authentication Information dialog box that corresponds to SMTP.

Note: Individual mailboxes need to use the full e-mail address as a verification information, you need to fill in the mailbox account a full e-mail address.

2, the server returns "553 error:authentication is required".

This is because the client software does not send messages using the ESMTP method, as long as the SMTP mail server requires authentication option is selected in the account properties. Even if the SMTP mail server requires authentication option is not selected, Foxmail will automatically attempt to send the message when it is sent, so this failure of sending is rarely seen in Foxmail.

3, the server returns "550:invalid user", "550:local user only" or "551 delivery not allowed to Non-local recipient".

If this occurs when you send a message in a normal way, this is because the server checks the sender's address and does not send the sender's address to a message that is not provided by this server. The solution is to open the Foxmail "Account Properties" dialog box and fill in the "email address" of "personal information" with the e-mail address provided by the mailbox system to which the SMTP server belongs. If the prompt appears when you use SpeedPost to send a message, it means that the other's mail server does not receive this speedpost delivery method, please use the normal way for this send.

4, the server returns "501 syntax.helo hostname" or "501 Invalid domain name".

The problem is with computer name settings because some SMTP servers do not allow the computer name to contain non-ASCII characters. In TCP/IP settings, your computer name should be a simple English name, such as ABC and so on, and then the DNS suffix is the same as your DNS domain. Changing the name of the computer will solve the problem immediately. Note that computer names cannot be used in Chinese, do not use infrequently used symbols, and should include the full DNS suffix.
