I have an issue with Postfix over port 465. Everything works smoothly over 587. When using port 465, it takes a long time for emails to be sent, whereas over port 587, email delivery is almost instant.
Additionally, it’s worth noting that the mail client takes 10-15 seconds to establish a connection before finally connecting to the server.
I’ve already searched through various forums but haven’t found a solution.
Does anyone have an idea what the problem could be?
