I quite often see posts like " Will application X work Ok with ISPc3?"
or "Will X conflict with my ISPc3 installation?"
What is the rule of thumb here?
Is it basically to avoid installs which mess with Postfix/Courier/Apache/php config files? How do I know if they do?
Avoid anything which installs another mail server, such as Zimbra?
Would be good to know
I'd love some comments here as well if you have a minute...
