My regrettable rashness in leaving "fetchall" in .fetchmailrc during
the first mail fetch on my new beowulf install has me chasing 91
lost or mislaid emails.
I also had no "mda" option in .fetchmailrc, so delivery to port
25should feed them to exim, I figure:
# lsof -i4:25
COMMAND  PID        USER   FD   TYPE DEVICE SIZE/OFF NODE
NAME
exim4   2278 Debian-exim    3u  IPv4   1545      0t0 
TCP greipner:smtp (LISTEN)
Although I had:$ more .forward
"|exec /usr/bin/procmail -t"
procmail does not appear to have run, as the .procmailrc from theold
host has not led it to disperse emails to any of a dozen mailboxes,and
there's no mail/log file.A It is there:
$ ls -l /usr/bin/procmail
-rwsr-sr-x 1 root mail 104404 Nov 17  2017 /usr/bin/procmail*

A "locate exim | more" does not elicit anything resembling a mail
destination.
Have I lost 'em, or are there still places to look?
In the interim, I'll ditch the "fetchall" and give "mda procmail" in
.fetchmailrca go Now I remember why I'm reluctant to update stuff.
