Here are what I have done
1. use zimbraSmtpPort changes port to 2525
2. edit master.cf, change
smtp inet n - n - - smtpd
to
2525 inet n - n - - smtpd
3. close port 25, open port 2525 on firewall
4. restart zmcontrol
After that, I cannot receive emails from outside, such as Yahoo, Gmail, etc. Did I do wrong way? Please advice
Thank you. |
