suggested Partition & Spam protection/Filter

[musa]

Hello ispCP community


i am planing to install a Server with ispcp and have 2 question.
i will run like 20-30 Domains on it from friends so no hurry in setting it up
and will for sure reinstall the server multiple times till i have the final "version"
still:

on a old vhcs server i remember i had a partition like
/
swap
/var/www
/var/mail


are these also default paths for ispcs or is something like /home/www
used to store user files?


also vhcs didnt had really spam protection (atleast not that i remember)
what would you suggest? saw in forum threds maia and amavis?

and also its possible to store SPAM mails in a SPAM folder (but with Mail quotas, so once its full other will get deleted, becouse i have some lazy user).

feel free to answer in german too.

thnx and greets
Musa
