     exactly what's reported by postfix, no extra information there


Jun 25 11:49:39 correio dovecot: lmtp(766, 
vanilson.parreira at domain.com.br): 645hNV7hqlP+AgAAHvf8vg: 
msgid=<F12DAC80721942C1842481355A0D08F8 at corporate.ad>: save failed to 
INBOX: Message was expunged (received-date)

     After analyzing lots of cases (made a script for doing that), this 
seems to occur only on messages with more than 1 recipient, usually on 
messages with lots of recipients (>10) altough i got some on messages 
with 2 or 3.


     Some days ago, when trying to optimize somethings on the server, i 
changed two dovecot parameters:

maildir_copy_with_hardlinks to yes
pop3_fast_size_lookups to yes

     previously, both were no. I have returned both values to 'no' and 
this situation, 'message was expunged' seems to not be occurring 
anymore. Can this behavior by any chance related to these settings ?
