I mentioned recently that IMAPS is being shut off for my work email. Well they just sent out a 2nd notice with some justifications. The one that JUMPS out at me is that (and I’m paraphrasing): “in order to provide POP and IMAP services we use approximately 50 IPs on our DMZ. “
Can someone with some insight into the inner workings of exchange explain why so many IPs would be required to provide these services? Thanks.
Hate to jump to conclusions, but, it sounds like whoever is in charge there doesn’t know how to properly setup load balancing. 50 IP addresses on the DMZ? That is .. a long stretch.
Agreed.
Another alternative is that this could be handled via NAT at the VERY least. Granted, that would be the dirt-cheap no-frills option, but it exists.
I agree that from what I have been told the people running our mail systems don’t have much clue. If I thought it would do any good I’d fight more to keep IMAP but apparently we just have under 4% of the users accessing mail via IMAP.
Instead I will use my energy to figure out a way to route around this problem.
