Yes:
Nov 15 16:17:20 Info: pop3-login: Login: user=<user9>, method=PLAIN, rip=x, lip=x, TLS
Nov 15 16:17:21 Info: POP3(user9): Disconnected: Logged out top=0/0, retr=5/84611, del=5/5, size=84524
Nov 15 16:17:39 Info: pop3-login: Login: user=<user9>, method=PLAIN, rip=x, lip=x, TLS
Nov 15 16:17:39 Info: POP3(user9): Disconnected: Logged out top=0/0, retr=4/63032, del=4/4, size=62963

As ~/Mail/INBOX. mail_location is this: mbox:~/Mail:INBOX=/home/%u/Mail/INBOX

For some time I had a readlink in the code so that dovecot would
definitely use /var/mail/$user but that didn't make a difference, at
least it happened again.

procmail in one case and exim directly in the other.

Checking the exim log, I see a mail being delivered to the user at
16:17:17, should be the 5th mail in the log . The next one is about 90
seconds later. This is the user with procmail. I don't have a log of the
one who's not using procmail. Also, concerning the timestamps, this is
all on the same host.



Thanks,
