Auto prune old emails

I look over the forum and I do search but didnt find what I was looking for.
So I would like to do automatic monthly prune of old emails of my customers.
For example.
I would like to automaticaly delete mails that are older than 6 months and which are in junk, trash and inbox folders, not deleting mails in other folders.
Is that possible and how.
I am new to linux so I would need detailed how to.
I am using ubuntu server 6.10 installed by this Falko how to http://www.howtoforge.com/perfect_setup_ubuntu_6.10

Thanks in advance

 

You can create a cron job that uses the find command: http://www.howtoforge.com/forums/showthread.php?t=7040&highlight=/usr/bin/find

 

Thanks Falko
So if I understand right then I make cron that will run once every month and the script should look like this

Code:

#!/bin/sh

for file in "$( /usr/bin/find /.junk -type f -mtime +90 )"
for file in "$( /usr/bin/find /.inbox -type f -mtime +90 )"
for file in "$( /usr/bin/find /.trash -type f -mtime +90 )"
do
  rm -f $file
done

exit 0

Am I right?
This script will look over the whole system to find this folders (junk, inbox,trash)and in those folders that are found, will remove files that are older than 90 days?

 

The script should look like this:

Code:

#!/bin/sh

for file in "$( /usr/bin/find /.junk -type f -mtime +90 )"
do
  rm -f $file
done

for file in "$( /usr/bin/find /.inbox -type f -mtime +90 )"
do
  rm -f $file
done

for file in "$( /usr/bin/find /.trash -type f -mtime +90 )"
do
  rm -f $file
done

exit 0

Also, are you sure that /.junk, /.inbox, and /.trash are the correct folders?

 

Not shure...
emails are in

/var/www/webXX/user/XXX/Maildir/cur There are already read emails
/var/www/webXX/user/XXX/Maildir/new There are unread emails
/var/www/webXX/user/XXX/Maildir/.Junk/cur There are junk-spam emails
/var/www/webXX/user/XXX/Maildir/.Trash/cur There are trash emails
/var/www/webXX/user/XXX/Maildir/.Sent/cur There are sent emails

So do yu think that kode shold look like this

Code:

#!/bin/sh


for file in "$( /usr/bin/find /Maildir/cur -type f -mtime +90 )"
do
  rm -f $file
done

for file in "$( /usr/bin/find /Maildir/new -type f -mtime +90 )"
do
  rm -f $file
done

for file in "$( /usr/bin/find /Maildir/.Junk/cur -type f -mtime +90 )"
do
  rm -f $file
done

for file in "$( /usr/bin/find /Maildir/.Trash/cur -type f -mtime +90 )"
do
  rm -f $file
done

for file in "$( /usr/bin/find /Maildir/.Sent/cur -type f -mtime +90 )"
do
  rm -f $file
done

exit 0

 

You must use /var/www/webXX/user/XXX/Maildir/cur then instead of /Maildir/cur, and so on.

 

That would be difficult, because I have about 27 domains and each domain has about 15 emails, so I cant write that for ever user, because there can be new email user any minut and I will not be notified about new user and I would like to automate that prune system.
Isnt there a way that system will look for all subfolders by that name and search files in that folders that are older than XX days?

 

You can try to use wildcards, e.g. /var/www/web*/user/*/Maildir/cur, but I haven't tested this.

 

OK

I try this tomorow. We will see then.

 

Okey

I try the script and wildcarts works

But there is other problem, I have luck that I tested on test box
Wel this is what happens.
When I run the scrip the script did search for folders and also the files but script delete all never files until date I put in in my case that was 28 of october so I have no new files but files older than 17days, stays in folders.

and that is the script I use

Code:

#!/bin/sh


for file in "$( /usr/bin/find /var/www/web*/user/*/Maildir/cur -type f -mtime +17 )"
do
  rm -f $file
done

for file in "$( /usr/bin/find /var/www/web*/user/*/Maildir/new -type f -mtime +17 )"
do
  rm -f $file
done

for file in "$( /usr/bin/find /var/www/web*/user/*/Maildir/.Junk/cur -type f -mtime +17 )"
do
  rm -f $file
done

for file in "$( /usr/bin/find /var/www/web*/user/*/Maildir/.Trash/cur -type f -mtime +17 )"
do
  rm -f $file
done

for file in "$( /usr/bin/find /var/www/web*/user/*/Maildir/.Sent/cur -type f -mtime +17 )"
do
  rm -f $file
done

exit 0

I tested on debian sarge, I belive on Ubuntu 6.10 is the same thing. Because Ubuntu 6.10 is in my production box.

 

Sorry, I don't understand the problem...

 

To tell shortly

Script delete new mails and not old, it work in reverse mode than I want to

 

Then try

Code:

/usr/bin/find /var/www/web*/user/*/Maildir/cur -type f -mtime [B][COLOR="Red"]-[/COLOR][/B]17

instead of

Code:

/usr/bin/find /var/www/web*/user/*/Maildir/cur -type f -mtime [B][COLOR="Red"]+[/COLOR][/B]17

Also have a look at

Code:

man find

 

I try - and + but, Its the same old files stays new were deleted. I did read man find, but dontknow how to help with that, I am not a programer so that is s little problem for me. But I saw there something about prune but didnt understand well. Could you help me.

 

OKey I did it

I use this script

Code:

#!/bin/sh

find /var/www/web*/user/*/Maildir/cur -type f -mtime +90 | xargs rm -f

find /var/www/web*/user/*/Maildir/new -type f -mtime +90 | xargs rm -f

find /var/www/web*/user/*/Maildir/.Junk/cur -type f -mtime +90 | xargs rm -f

find /var/www/web*/user/*/Maildir/.Junk/new -type f -mtime +90 | xargs rm -f

find /var/www/web*/user/*/Maildir/.Trash/cur -type f -mtime +90 | xargs rm -f

find /var/www/web*/user/*/Maildir/.Sent/cur -type f -mtime +90 | xargs rm -f

 exit 0

And dont forget to make executable file I name it mailprune.sh, then I make crontab that run once a month

Code:

crontab -e

Code:

 * * 1 * * /path/to/yourscript

I wrote that if someone would need that also, and dont know how to do it.

Thanks for your help Falko.

 

Is there a line I can put at the end of the script to recalculate the quota's, they don't appear to be refreshing?
