Hello there!
I had an ubuntu 16.04 vps server for 1 year now, I had some problems mostly due upgrading php-fpm 7.0 to 7.2 but that is not my problem now.
I rented a new server Ubuntu again but 18.04 which has by default php-fpm 7.2, the installation went fine, I moved the backups, installed them, switched IPs to the vps, same datacenter so I could use my old IP in my new machine.
All went fine but mail server!
I try to connect to the mail server and I get an error about certification, I redone certification, rebooted the server, restarted the mail clients but now I don't get any message at all!
I try windows 10 mail client, I try Outlook from office 2016 and I try thunderbird from my Linux laptop...all same problem!
If i sent e-mail let's say from gmail to my domains there, the mail is being delivered I guess, since I don't get a rejection reply, just my clients can't connect to the server at all!
Also the webmail address doesn't work at all! It says something about database failed to connect
Can I get some help here? Does anyone else had/have the same problem?

Ok so clearly ubuntu 18.04 is not supported 100% to this point, I went back to 16.04 had again same problem with dovecot and now I went to debian 9.5 which works as it should!
