25 port without SSL

Postby cvierilviv » Tue May 15, 2018 9:44 am

Hello,

I am using ZCS 8.8.8 and want to have 25 port for SMTP witout SSL but with authentication and stay with 587 for SMTP with STARTLS.

How can I make it work?

Hi. Smtp uses port 25. Mail Submission uses port 587 and support TLS by default.
