Best affordable business email hosting
*I need emails to come from user@company.com - it cannot be user@emailhost.com on behalf of user@company.com.*
I need our current Outlook folder structures to be the same on the iPhones and Outlook (read mails appear the same on both, moving an email from the inbox to a specific folder, etc.) It would be nice if the same thing happened in a webmail client as well.
I have approx 25 users in total - 5 have iPhones. The iPhone users outlook .pst files are between 2-5 GB. The remaining 20 users have about the same mailbox sizes, about 5 more would benefit from a IMAP setup and the rest would be fine with a POP3 setup based on multiple backups of the pst files.
gmail is out for requirement #1
mobileme is out for the same reason.
In house exchange is too expensive.
Hosted exchange is a little more than we want to spend (I've seen around $15 per user w/ a 2 GB mailbox limit. The majority of the users won't benefit from Exchange and I can't justify $4500 a year when we're using the included email hosting from our website hosting for $0.)
I checked our Fusemail and Simplicato. Both were the most affordable and seemed like the right fit. $2 per month per user w/ 10 GB and 5 GB storage respectively. I found a several bad reviews saying that both services were unreliable. Many of the those reviews said they went with Mailtrust and are much happier.

Calenders and contacts don't synch w/ iPhones. Push mail and instant sync is not supported w/ the iPhone. (Push email sounds nice, but the decreased battery life would probably stop us from using it.) If necessary, we can use the hybrid account - some users on hosted exchange around $15/mo and others on the basica imap account for $3/mo. The iphone users would get get all the features they want.
*Inhouse hosting*
We used to use IPswitch Imail, but stopped hosting it ourself when we got a virus. We can implement that again w/ some antivirus software, but that involves $1000 for a new workstation to run it (I don't think a P4 2.4 GHz workstation we have lying around will run it so smoothly.) It would be the cheapest the implement at around $1500.
A checked out a couple other packages, SmarterMail 5.x seems like a good alternative. It claims to have iphone over the air sync. It would be around $1500 - $2000 for the new workstation and software. It seems like a good alternative, but it comes with the headaches of hosting it ourselves. https://www.smartertools.com/SmarterMail/SystemRequirements.aspx Taking a look at that, it says the max incoming connection can be 10 on non windows server based setups. I guess that didn't affect us before because we used POP3.
Any recommendations? Any experience with the companies I mentioned?
