Here's a snippet from the procmail log file:
procmail: Notified comsat:
"user.domain.com at 0:/home/domain.com/homes/user/Maildir/new/1176426436.9170_1.east.domain.com"
I do not see any errors near the time the duplicate messages occurred.
In /etc/postfix/main.cf :
home_mailbox = Maildir/
mailbox_command = /usr/bin/procmail -a "$EXTENSION"
I'll try enabling the mail_log plugin.
