horde time off

Horde was not reading the default server time (all users were seeing UTC). I set the default in this config file:

/usr/share/psa-horde/imp/config/prefs.local.php

I added this line:

$_prefs[‘timezone’][‘value’] = ‘US/Central’;

delete email on plesk server

Posted on by

One of our customers had checked the “leave message on server” box, by accident in Outlook and over 8 months accumulated over 20,000 messages (mostly spam) on the server. The mailbox was close to 1.5GB in size.

Its a Qmail mail server.

First, find out exactly how many messages are in the box and sort by the largest message

ls -Slh | – less

The | less will allow you to go page by page. To exit type :q

He requested that we delete all the emails that were over 30 days old.

Then stop the server

/etc/init.d/qmail stop

Command to remove all the old messages:

find /var/qmail/mailnames///Maildir/curr -mtime +X -print | xargs rm

replace +X with the number of days (so in our case it was +30)

the Maildir/new folder contains messages in the queue.

Depending on how many messages are in the folder the above command can take a few minutes – do not cancel until you get back to the prompt $.

/etc/init.d/qmail start

Use mutt to bounce emails to a different account

Posted on by

Login to the server and (as root or the account owner) run ‘mutt -f /path/to/his/mailbox’. From there you can type a capital ‘T’ (for “Tag messages matching the pattern I’m about to enter”), you will then be prompted to enter a pattern to match. Type ‘.’ (to match all strings) and enter. All messages should have an asterisk (“”) next to them.

Now type a semicolon (“;”–the semicolon tells mutt that the action you’re about to take applies to all tagged messages) and a lowercase ‘b’ (for “bounce”. Together ‘;b’ means “bounce all these messages I’ve just tagged”).

You’ll be prompted for an address to bounce the messages to. Type it in and wait a little bit for all the messages to bounce (you may be prompted by mutt to confirm you want to bounce the messages). When mutt tells you that it’s done, you can type semicolon again and then a lowercase ‘d’ (for “delete”). Type a ‘q’ to quit mutt.
