I'm setting up a web/mail/source coude server for my open source project 
and am using FreeBSD.

My first concern is security. I read through the appropriate area of the 
Handbook and really enjoyed it. However, I do not know what suid, guid, 
and the like are. I've look up the man pages, but am still confused. It 
seems like the suid bit means that only the file owner can execute the 
file. Is this true? Also, does anyone have any security tips? I am new 
to all this and so am looking for as much info as possible. I would 
like to get a (few) book(s) on FreeBSD and security - any 

My second concern is performance. I read the tuning man page and was a 
little confused. Could anyone help me with this? Reasources and/or 
advice would be great.

I am using Apache/PHP/MySQL, eGroupWare, and SubVersion so far. I also 
need an email server. I will need mailing lists. I would like to 
support IMAP, but am unfamiliar with it. I understand POP3 as I have 
dealt with it for a while. What are the tradeoffs and/or advantages of 
IMAP? I know IMAP is supposed to be "newer" and "better", but how? In 
addition to mailing lists, contributors will also get e-mail addresses 
for the project. I'd like to use ClamAV for e-mail virus protection - 
but need some pointers for installation and configuration.

Right now I am running FreeBSD 5.4, Apache 2.0.54, MySQL 4.1, and 

Thanks is advance :-)
