Resolved Plesk 18.0.31/Centos 6 mails not sent any more 127.0.0.1[127.0.0.1]:10024: Connection refused

Hello,

My server is running Centos 6 (I can't easily upgrade it to Centos 7) with Obsidian 18.0.31.

Since few days server does not send mails anymore. Errors in maillog are :

delivery temporarily suspended: connect to 127.0.0.1[127.0.0.1]:10024: Connection refused

It is not related to amavisd (not installed). I restarted postfix and then the server but it didn't fix it.

Can it be due to obsolete version of openssl ?

Do you have Plesk Email Security extension installed? If yes - have you upgraded it?

I've totally removed this extension and mails are sent again. Thx Igor !
