Hi, Zhang Huangbin

In my company we have several versions of Microsoft Outlook 2003, 2007 and others. How can I enable ports 110 and 25 for internal network?

The other problem is this

Mar  7 15:35:28 mx postfix/smtpd[3585]: connect from DE-AdmREDs.holguin.geocuba.cu[192.168.2.24]
Mar  7 15:35:28 mx postfix/smtpd[3585]: NOQUEUE: reject: RCPT from DE-AdmREDs.holguin.geocuba.cu[192.168.2.24]: 504 5.5.2 <DEAdmREDs>: Helo command rejected: need fully-qualified hostname; from=<dto@holguin.geocuba.cu> to=<dto@holguin.geocuba.cu> proto=ESMTP helo=<DEAdmREDs>
Mar  7 15:35:28 mx postfix/smtpd[3585]: lost connection after RCPT from DE-AdmREDs.holguin.geocuba.cu[192.168.2.24]
Mar  7 15:35:28 mx postfix/smtpd[3585]: disconnect from DE-AdmREDs.holguin.geocuba.cu[192.168.2.24]

Both are enabled by default, but:

- Secure connection is required for port 110/143.
- No SMTP AUTH support for port 25. For internal use, better use another port and keep 25 for incoming mails. FYI: https://docs.iredmail.org/additional.smtp.port.html
