Hi
Therefore, i wrote a script that dives into the user's directories and
their maildirs. It looks like this
Just for reference I actually read the find manual one evening and figured
out the syntax (wahey!), then 10 mins later had forgotten it all again...
However, in the intervening mins I wrote this little script (watch out for
line breaks, find command should all be on one line). The -ls just means
that I can see it working and for debugging it means that at least you can
spot if it's gone off the rails... Remove the -ls and stick it in cron when
you are happy (obviously fix the start dir in this script though....)
#!/bin/bash
find . \( -wholename "*/.Spam/cur/*" -type f -mtime +7 -delete -ls \) , \(
-wholename "*/.Spam/new/*" -type f -mtime +7 -delete -ls \) , \( -wholename
"*/.Trash/cur/*" -type f -delete -ls \) , \( -wholename "*/.Trash/new/*"
-type f -delete -ls \)
I think the issue with mtime is that it gets reset when users open a folder
and mail moves from /new to /cur ?
Incidently here is a recipe to clean up large Sent Items folders... Use with
caution... It demonstrates finding files based on size, date and also
excluding one folder from being pruned...
find . \( -wholename "*/.Sent\ Items/cur/*" \! -wholename
"*/exclude_this_user/*" -type f -mtime +30 -size +5M -ls -delete \) , \(
-wholename "*/.Sent\ Items/new/*" \! -wholename "*/exclude_this_user/*" -type
f -mtime +30 -size +5M -ls -delete \)
For what it's worth, here's the cron script I run nightly: (No capital
'o's, they're zeros. That's to deal with spaces in filenames.)
# go through all users' Maildirs and delete deleted messages
# (*:?,*T*) - T is for Trash (Maildir flag)
# that are at least 30 days old
getent passwd | cut -d: -f6 | sort | uniq \
| perl -l0nwe '$_.="/Maildir"; print if -d' \
| xargs -0 -iI find I -type d -name cur -print0 \
| xargs -0 -iI find I -type f -name '*:?,*T*' -mtime +30 -delete
# delete all messages in Spam/Junk folders that are at least 14 days old
# (Note: doesn't look in '/new' -- procmail drops things directly to '/cur')
getent passwd | cut -d: -f6 | sort | uniq \
| perl -l0nwe '$_.="/Maildir"; print if -d' \
| xargs -0 -iI find I -type d \( -name '.Spam*' -o -name '.Junk*' \) -print0 \
| xargs -0 -iI find I -type d -name cur -print0 \
| xargs -0 -iI find I -type f -mtime +14 -delete
Best,
