Problem with iRedMail-0.8.3

Hi ZhangHuangbin,

This is highly appreciated if you kindly advise me the solution of my problem as below:

Problem #01. My iredmail server can not deliver and receive emails from some domains. In maillog i found "Connection timed out (in reply to end of DATA command))".

Problem #2. Configuring MS Outlook 2007 for outgoing server with port 465 and SSL doesn't work.

My Server configuration:

OS: Ubuntu 12.04 LTS 64bit (Core i7, 8GB RAM, 500GB Hard disk)
iRedmail version: iRedMail-0.8.3
Backend: MySQL
My server is behind a router with MTU 1500

Waiting for your positive response. Thank you.

Regards,
Russel
