Sqirrelmail，Postfix和Dovecot

Question

我已經安裝了Sqirrelmail，Postfix和Dovecot。 Sqirrelmail不會傳遞任何錯誤。沒有傳入或發送郵件。

其中「user1」是登錄到Sqirrelmail的用戶。

任何人都可以看到我的問題？

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
