Dovecot stopped inadvertantly yesterday night (following a system time adjustment) so during 12 hours before I restart Dovecot. During this time, - no email where collected in outlook clients - no error was detected by outlook clients
When I restarded Dovecot, things returned to normal, but emails sent during the blackout are not collected.
Looking in webmin / Postfix server / user mailboxes, I can see on the mailboxes summary indications like mail.jeanvieille (194.46 kB in 5)
When I go to this mailbox, it is empty.
Since I installed Virtualmin I tried to understand the logic of Postfix / Dovecot for filing mail related info but unsuccessfully. The following directories seemed to be involved (certainly not comprehensive): /home/user/.usermin/mailbox/ /home/user/homes/mail/.usermin/mailbox/ /home/user/homes/Maildir/ /Maildir/ /var/mail/ /var/spool/postfix/
Nowhere at these places I could find anything looking queued messages.
Thanks for help
