PostfixAdmin is a GUI which we use frequently to manage our users and domains in a Postfix system. Creating email aliases and “Forward only” redirections are the most regular tasks we carry out while managing it. Likewise, Roundcube is a free, convenient solution for the webmail demands and the vacation plugin is the indispensable component for enabling users to manage their own “Out Of Office” replies. Complete step-by-step setup guides can be found here for PostfixAdmin and here for Roundcube.

“queue file size limit exceeded” warning, Postfix Message Size Limit Mystery
When you send an email with a large attachment which you think it complies with the size limits designated inside your postfix configuration, you’ll most probably be still getting “Dec 14 21:35:59 mail postfix/smtpd[55736]: warning: D9105A1BAD1: queue file size limit exceeded” error message inside your server maillog. If this happens, you won’t even get a notification about the failure from Postfix itself, instead you’ll notice a quick Undeliverable message from System Administrator right in your client inbox which tells “552 5.3.4 Error: message file too big“, because Postfix has never accepted your mail.
