Sqirrelmail，Postfix和Dovecot

Question

我已经安装了Sqirrelmail，Postfix和Dovecot。 Sqirrelmail不会传递任何错误。没有传入或发送邮件。

其中“user1”是登录到Sqirrelmail的用户。

任何人都可以看到我的问题？

Update, I can now send mail to external domains, but not receive from external domains. 
But user1@mydomain.com & user2@mydomain.com can send and receive emails to each other. 

MX record exists: 
10 @ mail.mydomain.com 1 Hour 
0 @ smtp.mydomain.com 1 Hour
