plesk 12.0.18 - TLS encryption for outgoing mail

[Carlo Osenda]

hello ... I just installed a vps plesk 12.0.18 and I have a problem with the SMTP . They run this ONLY with TLS encryption and do not know how to exclude it .
The same problem existed with the incoming mail but thanks to a post which indicated the procedure to root I could edit it.
Give me a help ... thanks

It seems you are using Postfix. What version of Postfix currently you have in the server?. Not sure below given links are valid or not?. Please read through and verify.
