Topic: Can POP ports 110 & SMTP port 25 be made secure ? (Same as 995 & 587)

==== Required information ====
- iRedMail version (check /etc/iredmail-release): 0.9.6
- Linux/BSD distribution name and version: Centos 7
- Store mail accounts in which backend (LDAP/MySQL/PGSQL): LDAP
- Web server (Apache or Nginx): NGINX
- Manage mail accounts with iRedAdmin-Pro? Yes
- Related log if you're reporting an issue:
====

We have an issue with clients working in a country where POP3 port 995 is blocked and SMTP port 587 is blocked. I found out that Dovecot cannot be made to listen on multiple ports.

As an alternate solution, can ports 110 and 25 be configured for POP3-s, and SMTP TLS ? Essentially so they would act exactly the same as ports 995 and 587 ?

With default iRedMail settings:

*) port 110/143 are open and TLS is required for secure connection - so it's secure.
*) port 25 is used to accept incoming emails only. If you want to enable SMTP AUTH for sending email, please follow this tutorial: http://www.iredmail.org/docs/enable.smt … rt.25.html
