Exim or Dovecot quotas with Pigeonhole

 As soon as you enable Pigeonhole with Exim and Dovecot you get email quotas not working any longer. And here is a way how to enable them back with Dovecot. 

Enabling quota plugins in Dovecot

Update configuration file /etc/dovecot/dovecot.conf:

Add lines

    quota = maildir:User quota
    quota_rule = *:storage=10M

to plugin {...} section

plugin {
    sieve = ~/.dovecot.sieve
    sieve_global_path = /var/lib/dovecot/sieve/default.sieve
    sieve_dir = ~/sieve
    sieve_global_dir = /var/lib/dovecot/sieve/global/

    quota = maildir:User quota
    quota_rule = *:storage=10M
}

Update mail_plugins line in protocol lda {...} and protocol lmtp {...} section to the following:

mail_plugins = $mail_plugins sieve quota

Add line

mail_plugins = quota

into protocol pop3 {...} and protocol imap {...} sections:

protocol pop3 {
    mail_plugins = quota
    pop3_uidl_format = %08Xu%08Xv
}
protocol imap {
    mail_plugins = quota
}

Converting passwd-files to contain quotas data (since Directadmin 1.43.1)

To enable DA to add the quota options, add:

add_userdb_quota=1

to your directadmin.conf, and restart DA. The internal default is 0.

After turning on the option, to convert all existing files to use the extra format, use one of these new task.queue command:

echo "action=rewrite&value=email_passwd" >> /usr/local/directadmin/data/task.queue

If you need to convert the file only for one user, use this command (replace fred with your real username):

echo "action=rewrite&value=email_passwd&user=fred" >> /usr/local/directadmin/data/task.queue

Converting passwd-files to contain quotas data (prior to Directadmin 1.43.1)

Download a script (no more needed since Directadmin 1.43.1 is released):

# cd /usr/local/directadmin/scripts/custom
# wget -O poralix_transform_passwd.sh http://plugins-da.net/_public_files/poralix_transform_passwd.sh.txt
# chmod 700 poralix_transform_passwd.sh
# chown diradmin:diradmin poralix_transform_passwd.sh

And update (or create):

• /usr/local/directadmin/scripts/custom/email_change_pass_post.sh
• /usr/local/directadmin/scripts/custom/email_create_post.sh

# cd /usr/local/directadmin/scripts/custom
# touch email_change_pass_post.sh email_create_post.sh
# chmod 700 email_change_pass_post.sh email_create_post.sh
# chown diradmin:diradmin email_change_pass_post.sh email_create_post.sh

so both of them contain the following lines:  

#!/bin/bash
/usr/local/directadmin/scripts/custom/poralix_transform_passwd.sh ${domain} >/dev/null 2>&1;
exit 0;

To update the existing files, you should run the following command:

# for domain in `cat /etc/virtual/domains`; do /usr/local/directadmin/scripts/custom/poralix_transform_passwd.sh $domain; done; 

Have a nice day!

UPDATE:

Since a recently released version of Directadmin 1.43.1, you no more need to use any custom scripts (posted above) to have quotas in dovecot password files. It's a new built-in directadmin feature.
