Apologies if this is a stupid question but I'm setting up a new server and no longer want any mail server running.
All hosted websites will use an external mail delivery system (Google Apps/Zoho Mail etc) so postfix becomes redundant and due to recent hacks on another server with spam delivery I'd rather keep postfix turned off completely.
However, how would system emails be delivered? Is there anyway to tell webmin/virtualmin to use an external SMTP mail to send system mails. By system mails I mean the likes of CSF firewall notifications, server/system monitoring etc.
I can see an option in server/system monitoring to use SMTP mail host but there's no login options or port settings?
Does anyone know of any documentation on this or any strong reasons why its not a sensible idea to turn off the mail server if its not needed?
