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???
You can try the message_size_limit parameter in /etc/postfix/main.cf: http://www.postfix.org/postconf.5.html
but how can i change that number in phpmyadmin? in the guide i create a file: /etc/postfix/mysql-virtual_mailbox_limit_maps.cf i don't know enough about it but i think this file enables changing the quota settings in postfix with phpmyadmin. can i create a file: etc/postfix/mysql-virtual_message_size_limit.cf and then be able to change the size in phpmyadmin ???
