plesk postfix/smtpd[2501]: SSL_accept error from sender.example.com[203.0.113.2]: -1

plesk postfix/smtpd[2501]: disconnect from sender.example.com[203.0.113.2] ehlo=1 starttls=0/1 commands=1/2

Cause

The sender server uses deprecated protocol SSLv3 that is disabled on Plesk servers with Postfix for security reasons.

Resolution

It will be possible to receive emails just after the SSLv3 protocol is disabled on the sender's side.
