Greetings
I updated the OS in a VPS blindly and broke the mail service. I had set
up this service over four years ago and never had issues with upgrades
until recently. I realized the gravity of my mistake after dovecot
refused to start. Version 2.4.1 had arrived and I am in so much trouble.
So far, I have adapted the configuraton files to 2.4 standards. "doveadm
auth test user" tells me that the authentication is working fine. I am
able to view old mails via doveadm. However, I get nothing new from mail
clients. The maillog tells me that mails are getting queued (why?). I
see status=sent (250.2.0.0) in some transactions, but that is the extent
of success. However, I still get a nagging error message (see the end of
this mail).
dovecot -n
# Pigeonhole version 2.4.1-4 (0a86619f)

I did adjust an entry in postfix (master.cf). I switched from dovecot-lda
to dovecot-lmtp. LDA was throwing permission errors when accessing the
cert file. Most reference materials recommended LMTP because its processes
already have the required privileges. So ...
master.cf (postfix)

What am I missing?
