[SOLVED] Smtps

omidg · 06-08-2017, 12:06 PM

Hello, I use CentOS 5.11 and I have Sendmail running and not Postfix. Port 465 (smtps) is open and listening, but I don't think it is Sendmail because I have not configured it in Sendmail. Even when I stop Sendmail, port 465 is still open. Is there any other service that could be listening on port 465? I want to find out what service. Please help.
