Sorry to say this setup works flawlessly for years. The only addition we
will make now is to do the delivery with dovecot-lda. Everything else
(including multiple dovecot pop/imap servers) will stay as is.
Hopefully dovecot-lda does not fiddle around with the indexes too much, as we
then would have to delete this part of the code out. It is not needed as we
found out during the last 10 years of delivering mails into the maildirs by
atomic rename action while dovecot is presenting them over imap.
