IMail is a good product, but as with anything else, whether it's the right product for you depends on what you plan to do with it, etc, etc. For example, if you are looking to set up a new mail server, you can't purchase iMail. You have to purchase the Ipswitch Collaboration Suite (ICS), which includes iMail, Groupware, Instant Messaging, and it's own integrated Anti-virus. The anti-spam tools included in ICS are better than previous versions, but not as good as the declude add-on (
If you are looking for a simple windows hosted mail server, there are other, equally good mail server programs:
SmarterMail (
Many iMail users defected to Smartermail when ipSwitch declared "no more stand-alone iMail". Most seem to be pretty happy, and delcude also integrates with SM, so you can have very good anti-virus and anti-spam.
Merak Mail (
Some former imailers went with this as well; I suspect it scales better than iMail or smarter mail for thousands of mailboxes, especially if you use IMAP or Webmail, but I have no hard data to prove it
Kerio Mail (
This is the one we switched to from iMail. I liked the broad choices for anti-virus integration, the anti-spam tools work pretty well. For us, the tipping points were IMAP performance & the web mail client. We use IMAP exclusively in our environment, and Kerio's was hands down the fastest on the same hardware. Also, the web client is very outlook-like, and easy to use.
Hope this helps
