Hi all
My name is Jochen and I have joined the list in order to get some first hand advice on my journey of migrating my SOHO mail server from 2.3 to 2.4.
I set up my first server back in 2005 or so. OpenSuse and Cyrus IMAP. That went fine until all of a sudden, some 8 or 10 years ago, Suse no longer supported Cyrus directly. So I switched over to Dovecot and did not regret it. My current production server (OpenSuse Leap 16, Dovecot 2.4.2) is running fine after a recent migration. But the HW is ageing and disk usage is getting close to 80%. So I got new and larger HW. I run OpenSuse Leap 16.0 and Dovecot 2.4.2 on it. As I ran into unsurmountable problems there (could not move mail_path away from /var/mail), I decided to set up a test system under Ubuntu server 25.10. There I have got Dovecot running much better, but still, I ran into problems I could not solve for quite some time now. So here I am.
I will start with questions about Dovecot on Ubuntu - my test system - because there I hope my mistakes are not as bad.
Welcome to the list, Jochen.
- Why did you not just migrate your OS to the new server. Would have been a lot easier just running dd and then doing growfs to fill the new disk.
- We are waiting for your questions on Dovecot on Ubuntu :)
