Subject: Security on Sendmail vs Qmail

Hello all,

I'm relative new to Linux world (I came from NT... ), so there's some
things, maybe extremely easy that I'm missing. One of that things is
security on mail systems.

I think that one of the most popular linux mail packages is Sendmail. But I
heard that sendmail is not completely secure, may be due to some buffer
overflows... I'm not sure. Someone told me Qmail is much more secure,
compared to Sendmail. Honest, I've no idea ;-)

I take a look at one book which I found to be very good "Securing &
Optimizing Linux: Red Hat Edition" at http://www.openna.com/books/book.php
and they write about Sendmail, so I think I can deduce that Sendmail is
secure enough.

Question: I don't what to now which is the best mail software, or if
Sendmail is best or worst than Qmail. The only thing I would like to hear
from you is which package has security enough to be installed in a company
that don't want to have the email hacked?

Many thanks,
Luis Gonzaga
