I thought this would be a little easier to find but I seem to be having difficulties.
I am looking for a web host with the following:
--IMAP access for e-mail
--At least 10 GB disk space (more important to me than data transfer)
--Ability to host at least 3 domains under one account (with both combined and separate control panel access for each account)
--Under $30/month. I'm not looking for the cheapest. Quality of the company is far more important.
You have a very good budget for what you're looking for. As for the IMAP, I think you shouldn't have problems with that (I always thought it was kind of a mail standard :-\, but who knows) -- just find out what mail server a host is using and check out if it supports IMAP, or the super easy way -- e-mail the sales team!
