If the client base wants to stick with basic IMAP/POP3 email Tucows/OpenSRS has a good platform.  Also a few years ago my company migrated business email accounts and domains from an ISP and moved them to Office 365 and did a revenue share with the ISP.  They where happy still got a bit of revenue  but did not have to support it.

I hope this isn't too far off topic for this list.

We acquired a small ISP a couple years ago that has its roots in the "local ISPs" of the 90s. This ISP is still hosting email and web services for customers both on company domains as well as customer domains. There is some decent revenue coming from these services, but cost of maintenance is becoming a challenge. We are looking at migrating to another platform or completely discontinuing those services.

I'm wondering if others here have gone through that process and have any advice as to how to go about it.
