Re: Good commercial e-mail software packages for UNIX?
Sorry, just to clarify, looking for something on the server side... I understand the OSS options clearly, I am looking for something a little more "small business oriented" in terms of installation and management. Ensim, plesk, etc. are really not viable options when you're explaining to a secretary the difference between POP and SMTP.
I used to recommend CommuniGate frequently, but with the new license structure, its not really geared towards small business. I was lucky enough to have purchased a 2000 seat license a few months before the went to the 4.2 license scheme where groupware was rolled in. My 2000 seat license for email cost under $2000, and supposedly included unlimited upgrades, but once they released 4.2, groupware was no longer optional and the price for the same license would be closer to $20k.
I guess I made out pretty good, but now upgrades/support is priced at 19-24% of the new purchase price per year, so at some point I'll probably be looking to migrate away from it because its tough to justify $4000 a year for support when your just using it for pop/smtp
As a product, its a fantastic mailserver. Reliable, stable, feature rich, and easy to admin.
