Localhost imap server fails after upgrade from 2.2.33.2-1 to 1:2.3.2.1

Mon Dec 31 17:53:14 EET 2018

Hi Aki,
(This message might not make it to the list; I have to switch back to the
other dovecot to be able to send from that address)

Oops; I did not think carefully enough about your instructions. Here is the
output from

$ dovecot -n -c /home/meuser/dotfiles/auto-stanford-dovecot.conf

# 2.3.2.1 (0719df592): /home/meuser/dotfiles/auto-stanford-dovecot.conf
# Pigeonhole version 0.5.2 ()
# OS: Linux 4.18.0-13-generic x86_64 Ubuntu 18.10 ext4
# Hostname: cpbl-t450s
doveconf: Warning: please set ssl_dh=</etc/dovecot/dh.pem
doveconf: Warning: You can generate it with: dd
if=/var/lib/dovecot/ssl-parameters.dat bs=1 skip=88 | openssl dhparam
-inform der > /etc/dovecot/dh.pem
mail_location =
maildir:/home/meuser/imap/gmailStanford:LAYOUT=fs:INBOX=/home/meuser/imap/gmailStanford/INBOX
service stats {
  unix_listener stats-writer {
    mode = 0666
  }
}
ssl_dh =  # hidden, use -P to show it
verbose_proctitle = yes

I then followed the instructions in the Warning lines above and now I get:

 dovecot -n -c /home/meuser/dotfiles/auto-stanford-dovecot.conf
# 2.3.2.1 (0719df592): /home/meuser/dotfiles/auto-stanford-dovecot.conf
# Pigeonhole version 0.5.2 ()
# OS: Linux 4.18.0-13-generic x86_64 Ubuntu 18.10 ext4
# Hostname: cpbl-t450s
mail_location =
maildir:/home/meuser/imap/gmailStanford:LAYOUT=fs:INBOX=/home/meuser/imap/gmailStanford/INBOX
service stats {
  unix_listener stats-writer {
    mode = 0666
  }
}
ssl_dh =  # hidden, use -P to show it
verbose_proctitle = yes

However, this does not help my primary symptom:

$ /usr/lib/dovecot/imap -c /home/meuser/dotfiles/auto-stanford-dovecot.conf
imap(meuser,)Error: net_connect_unix(/var/run/dovecot/stats-writer) failed:

Thanks!
Chris
