Hi Timo, i have a few ( not really many ) errors like this with lmtp
Jun 7 09:41:23 mail02 dovecot: lmtp(11034, user@user.de): DELlOoq+7U0aKwAAZA6IsQ: msgid=<4DEDD502.705020@ameriton.com>: save failed to INBOX: BUG: Unknown internal error
Something went wrong. Really shouldn't be happening.

Did this also get some error before that log line? Something went wrong with finding the message's UID during saving..
havent super verbose logging enabled yet, this servers are massive in production with huge logs, lines found out by grep looking deeper by editor to the log i would say mail is stored whatever uid error was before and wasnt reported before ( with this small verbose )
any idea ?
dovecot -n output would help guessing the reason.

is it critical, possible to loose mails with this ?
Shouldn't be possible to lose mails.
nobody reported it so far
i have a nearly equal setup with same errors but more rare ( not so much traffic/mailboxes )
here i found with more verbose logging
