Outlook Express was unable to send a mail prompt to find the host "smtp.163.com"

There are many advantages to using Outlook Express to send and receive mail. You can manage multiple emails at the same time and view new emails at the same time. However, after setting, I found that my computer could not send emails, indicating that the host could not be found. smtp.163. Com”. Please check if the server name entered is correct. Account: 'pop.163.com', server: 'stmp.163.com', protocol: SMTP, port: 25, secure (SSL): No, socket error: 11001, error number: '0x800CCC0D'.

Excuse me, is this a problem with the mail server, or is there a problem with my mailbox settings?

This is because many users make spelling errors that result in incorrect account settings. The sending server can't simply fill in “smtp”; the same reason, the receiving server can't simply write “pop3”. Take the 163 and Sina mailboxes you mentioned as an example: the sending server of 163 should be filled out as “smtp.163.com”, and the receiving server should fill in “pop.163.com” instead of filling it into “stmp” .sina.com” (This is Sina's sending server), Sina's receiving server is "pop.sina.com". After this setting, there should be no problem in receiving emails. In the future, different email providers will not be the same. !
