i have followed this howto: http://www.howtoforge.com/virtual_postfix_mysql_quota_courier_ubuntu_edgy and everything is working like it should. since it is storing all the email addresses, passwords, quotas etc in a mysql database i have made a tiny webmin thing so i can create new email addresses etc. through the browser. is it possible (and easy) to administer the size allowed for attachements in the same way as i administer quota???
