Cloudpanel + Mailcow SSL/TLC for Thunderbird

noherenotnow

Hello.
I have installed cloudpanel on debian12 and mailcow as revers proxy with standard install parameters.
Then i got Let’s encrypt SSL from cloudpanel for mail.mydomain.com
For now everything works good except mail clients like Thunderbird etc.

Thunderbird cant’ got SSL/TLC. Only STARTTLS.

in my mailcow.conf i had done this:
HTTP_BIND=127.0.0.1
HTTP_PORT=7080
HTTPS_BIND=127.0.0.1
HTTPS_PORT=7443

As i understand, for now my cloudpanel cert for mail.mydomain.com
and mailcow auto-generated lets encrypt cert are different.

So what i must to do ? (just copy form where to where ?)

Thanks and sorry for my bad english.!!!

You can get better understanding by reading this https://www.mimecast.com/blog/ssl-vs-tls-vs-starttls-encryption/

about protocol of STARTLS and SSL/TLS

See this script, it essentially does what you want. You just have to adjust your paths accordingly

Thanks a lot.
I have copied certs manually, then run this commands:

postfix_c=$(docker ps -qaf name=postfix-mailcow)
dovecot_c=$(docker ps -qaf name=dovecot-mailcow)
nginx_c=$(docker ps -qaf name=nginx-mailcow)
docker restart ${postfix_c} ${dovecot_c} ${nginx_c}
