Zimbra

[Marcus Maximus]

Has anybody here used Zimbra in a business environment, roughly 25-30 employees.

We were looking at the prospect of selling our exchange license, if we can and migrating to Zimbra. The main concern i have is speed as its web based.

Another option in case your not aware is Google offers email hosting for business & education. Education is free but you might like to look into the costs for business. Then they offer web based plus POP and IMAP. http://google.com/a
Very simple to setup then you don't need an internal server.

One of the main reasons we were looking at it was push emails to phones at very little extra cost per month.
