Mailbox connection fails: Connection closed (No commands sent) Help please

[postfix at aecperformance.com]

OK I'm confused. It looks like I'm connected to the mailbox but when I try to 'Get Messages' now it says that the server has disconnected.

In the mail.log file I see this (again):

Dec 8 12:55:43 softlinksys dovecot: imap-login: Login: user=, method=PLAIN, rip=67.8.3.170, lip=194.163.45.150, mpid=67110, TLS, session=

Please help me.

How can I fix this problem?

That error's happening because you (Alexander) are using an old openssl version that has the problem described on:

 

   <https://www.openssl.org/blog/blog/2021/09/13/LetsEncryptRootCertExpire/> https://www.openssl.org/blog/blog/2021/09/13/LetsEncryptRootCertExpire/

 

That's not the problem that the original poster is having unless Thunderbird also has the same problem, which it may; see:

In any case, this works fine with OpenSSL 1.1 or later:

 

  $ openssl s_client -connect mail.sizzelicks.com:993

  ...

  * OK [CAPABILITY IMAP4rev1 SASL-IR LOGIN-REFERRALS ID ENABLE IDLE
