Yes, I understand that. I'm just a bit unclear about how the POP3 and SMTP is delivered.
As there is a single mail-server, does POP3 and SMTP for (say) mail.mydomain.com (on its own IP address) get throttled according to that IP address's kbps setting, or not?
I am presuming it does, just want to be sure.
The problem: A couple of customers are hammering the system with vast mail transfers (big attachments, not spam). Transfer voloume is not an issue, but bandwidth is. Will putting them on separate IPs and throttling them solve the problem, or do I need a third-party software solution?
