Mac comes with mail client can only accept unable to send mail problem resolution

Usually office use Mac client more, their own 163 and Gmail are in the Mac down to send and receive mail, also accustomed to the layout of Mac Mail, in the new company configuration office mailbox, suddenly appeared in the office mailbox can only accept, can not send embarrassing situation .....

First introduce the general situation of the Office mailbox

Our mailbox is used 163 of the enterprise mailbox, and put our own domain name cname to 163 of the mailbox transceiver domain

For example, our domain name is: linuxtea.com

Pop Address: pop.linuxtea.com

SMTP address: smtp.linuxtea.com

IMAP Address: imap.linuxtea.com

We have our own mailbox domain name CNAME to 163 enterprise mailbox on the sending and receiving domain name, as follows:

Pop.linuxtea.com CNAME pop.qiye.163.com.

When configuring the mailbox, the POP,POP3,IMAP protocol has been tried, that is, unable to send mail, there are two problems, resulting in a connection is not and can not send mail

First, when entering the mailbox user name, must lose the whole,

That is, the user Zhang San mailbox user name must be: [email protected] and not for Zhangsan

Second, in the input mailbox to send the address, cannot write smtp.linuxtea.com, but must write smtp.qiye.163.com

This does not know what the cause, if the use of the CNAME after the smtp.linuxtea.com domain name as an SMTP domain name, and then no longer send the mail, but instead of the SMTP domain name of the enterprise mailbox, the problem solved

Looks like a lot of business mailbox will exist this problem, and self-built mailbox or relatively large 163, QQ, Gmail, this problem will not occur.

I hope this article will help you.
