Hi all,
I use a local Dovecot IMAP server to store all my emails, which I
access from either Claws-Mail or Evolution. On 7/7/2025 my email
stopped working, a few hours of troubleshooting led to a Dovecot
problem, a few more hours led to the 2.3 to 2.4 config file changes,
and the next 3 days I went without email while trying to get a working
2.4. Finally I managed to downgrade back to 2.3.x and restore the
config from backup, and didn't lose too many emails.
I've waited 6 months for all the dust to settle, and now I'm going to
try to make a test VM (Void Linux) with 2.4.x, using phony baloney data
because I don't want to lose my email capabilities again.
So my first question is this: Is there a lint utility for my
configuration, so that I can cut down on experimenting with 50
different variables at once and reading conflicting documentation?
Here's what I know so far about lint utilities:
* I know doveconf -n and dovecot -n dump non-default settings, but I
don't think they can detect syntax errors.
* dovecot-sysreport doesn't seem to give me info about syntax errors.
* None of the doveadm commands seem to check syntax.
Thanks,
