Hello Timo and Urban, and thank you for the very quick reply
I have already thought about these things: I have already disabled
mailbox deletion from POP3 clients, that actually just leave the
messages on the server
however, this time noone of the 4 recipients got the email - so it is
really strange that all che clients deleted the same message and left
all the others
we can notice this only a few days after the issue, because customers
send us a reminder forwarding the lost mail

maybe something related to LDAP lookups? what can happen if for some
reason the LDAP server does not reply to the lookup?
Timo, belive to me, I use dovecot since 3 years, and I am one of the
thousands of happy user, I really can't explain what is happening on
I'll do this trial: I'll enable lda debug logging ont a file on a USB
hard disk - in order to know where exactly messages are stored, and
enable also maillog too
I'll keep you informed on what I'll find - maybe it will take some
days, as I told it happens quite seldom
