I need to connect one of my mailboxes with older web application, that supports smtp communication only on port 465 (SMTPS protocol). It is unable to communicate via STARTTLS (port 587).
How should I go about it in miab? What settings/files I need to change?
Will changing /etc/postfix/master.cf - uncommenting “smtps” line suffice along with allowing port 465 through firewall? Or do I have to change anything else to make it work?
Thank you very much in advance for any tips!
All the best.
