Thanks for making me sensitive to this!
Are you referring to the files in /var/spool/exim/db?
drwxr-x--- 2 nobody nobody 4096 Sep 16 2004 .
drwxr-xr-x 7 nobody nobody 4096 May 27 18:03 ..
-rw-r----- 1 nobody nobody 552960 Nov 9 12:01 retry
-rw-r----- 1 nobody nobody 0 Sep 16 2004 retry.lockfile
-rw-r----- 1 nobody nobody 45056 Nov 9 11:48 wait-remote_smtp
-rw-r----- 1 nobody nobody 0 Sep 16 2004 wait-remote_smtp.lockfile
If so I will remove them right away!
Would it be worth the while to delete them with a monthly crontab?
Thanks
Nico
