Actually, yes sendmail can be made resaonably secure... but if you want
performance, sendmail is really not the choice you want to go with.
Postfix and qmail both have much smaller memory footprints on the system
and are more efficient in terms of cpu time. To give you an example... I
run a mail list that has some 240k subscribers. Running sendmail, this
machine would routinely hit load averages of 30 or higher. Switching to
Postfix, the box seldom goes higher than a load of 6!

I've used sendmail for a long time... in fact starting with version 4. I
know how to configure it, and on small systems, it is just fine. But for
larger industrial use... you either need an large industrial computer or a
lighter MTA.

->>That doesn't look to old to me. To be correct actually, sendmail has done a pretty good source code audit of sendmail. They've also added alot of features to help improve security. The reason most people switch to qmail is because they cannot figure out the sendmail configuration as its pretty confusing. Sendmail can be made "secure" easily. Sendmail has been around since the beginning of time yes, and it has had its share of major security problems, but I do feel that a properly configured sendmail box will outperform qmail. Not to mention that sendmail has alot of the features needed by big companies whereas qmail does not. I do not want to start a "sendmail vs. qmail" war here, I just hate seeing people spew crap out of their mouth about issues like this.
