Very pressed for time here so some quick questions if you dont mind.
Using Zimbra 5.0.9_GA_2533 Ubuntu8 64bit - FOSS edition
Followed the single server install and also blocked all ports except 80/443/25 and 465
Added obvious user security stuff like password lockout after 3 attempts.
I am not sure whether I have it all covered, is this secure to go live with the web GUI on the internet? I was going to keep it intranet only and just expose SMTP.
Can any of you more experienced users who have had time with this see any (potential or known) problems here?
