Hi
Well, it can be rebuilt, and a backup from 2019 is that, did unfortunate not help this time.
this is the only error I manage to find:

the big question is why my computer reach mail server when on OFFICE LAN and not on HOME LAN? Same internet provider (get.no) and same mail provider. Only difference is router config:
HOME pfSense + bridged get.no router
WORK only get.no router.
Reason I mention SSL certificate is that it is information you forum useres may understand and connect to my mail issue. Mail provider write on his home page:
"Use of encryption (SSL)
If you wish, you can use encrypted connection to the mail server. Note, however, that your e-mail server does not have its own so-called SSL certificate, but shares this with other customers. You will thus get a warning in your e-mail reader the first time you activate SSL which says that the certificate does not match your domain name. You must accept the certificate then presented before you can use SSL."
