All OSes have their security problems, even the famous
OpenBSD.  I would agree that OpenBSD is probably the
best choice for a person that is going to use the
default install, but if aren't familiar with what your
using, that can be risky.  

We just recently installed Solaris on our new
production server, and out of the box, it is far worse
off than RH in my opinion.  It had just about ever
service turned on.  That's not necessarily a bad
thing, unless you aren't one to lock down your system.


Use what you are familiar and comfortable with.  If
you know Linux, and, more importantly, know how to
secure it, use it.  Same thing for Solaris  and *BSD. 


To answer your original question, I've used qmail on
RH 6.2 for awhile now without any serious problem. 
The only problem I ran into was with Norton ghost and
RH 6.2.  Between 6.1 and 6.2, RH switch from a 1K to a
4K cluster size and Norton Ghost didn't like it (I
ghost everything so I can easily restore if needed). 
My qmail server has been up for over 100 days now.
(that's not very long, but that is when I originally
installed it).

A couple of suggestions, first increase the the
/proc/sys/fs/inode-max value (I believe I set mine to
16384, but you should base your values on the amount
of RAM you have).  I ran out of inodes at one point,
but I increased the value and went on without any
trouble. 
More importantly, don't forget to apply all necessary
security fixes from RH's web site.

I don't know about RH 7.0.  From what I've been
reading, I would recommend staying away from it for
now.

I hope this helps,
Steve
