We have been using a Linux based product called Netpilot for the last 6 years and while it has always done it's job brilliantly in the past,it has now begun to show signs of not being able to cope with the volume of mail passing through it and the number of users now connecting.
We are looking for an alternative that isnt going to cost the earth (so exchange is out of the question).
Someone has recomended Kerio mail server, but I have never heard of it nor used it before and was after some recomendations and feelings from some of you sys admins who are already using it.
What sort of problems have you come up against? how have you found support services? what do you love/hate about it?
Also I have just downloaded the 30 trial so we can have a play, but was wondering how do you test a mail server without re-routing your incoming mail to it? We obviously cant do that as it would mean losing access to email while we setup and tested Kerio?
Also can someone confirm that Kerio will fulfil the following criteria:
1) Shared contacts
2) Shared calendars
3) Inegration with outlook 2000/outlook expresss (can you use shared calendars and contacts with outlook express?)
4) Highly scalable? 500+ users
5) Very stable, once it is configured and running I dont want to be having to mess with it each day.
Thanks in advance guys!
