When deleting a domain, dovecot.conf isn't updated

[ruzakuku]

After deleting a domain using Virtualmin, we saw that at the next server reboot Dovecot didn't start. Log files show that the old entries (certificate location) of the deleted domain weren't deleted in dovecot.conf.

We removed the old entries, dovecot started.

Hello,

Could you share the records that you deleted in Dovecot?

[ruzakuku]

Sure !

local_name domain.com {
ssl_cert = </home/domain/ssl.combined
ssl_key = </home/domain/ssl.key
}

domain is the considered domain name of course.
There were 2 removed domains, both lines had to be manually removed.

If it is useful, SSL is supplied by Let'sEncrypt certs.

Does this happen consistently if you create and then delete a domain?

Well, I did it again with a new domain, created and deleted, this time all was going normally, lines were added then removed.

The problem happened on 2 domains that were active a few years, then I put them inactive and finally deleted them. I assume the problem happened when I deleted them, then I rebooted some days later after a kernel upgrade and saw that Dovecot couldn't start. Earlier reboots (before deleting the domains) were fine.

Were the records you removed from dovecot.conf the same format as the ones that get added if you create a new test domain?

Yes.

Hmmm .... it's hard to debug this further unless the problem happens repeatably.
