Having used and configured both Send mail and Postfix, sendmail was and

of Windows and a Mac, there are bunches of Windows machines in the world
so every little hacker writes viruses for them. There are very few Mac
Viruses...
I'm sure there are more people writing hacks and cracks to break into
sendmail more so than Postfix, so in the scheme of things Postfix may
just be a better choice. Like Mozilla over IE... Thunderbird over
Outlook....
Sure, but to be fair Sendmail was essentially the first. There
haven't been any security issues in a while, and the last few were
not as significant as the issues prior to 12.X when the submit thing
was added. I think any of the MTAs are subject to hacking, the
source for all is available. The hard core hackers seem to have all
grown up, all I see these days is script kiddies in China trying to
run dictionaries against the root account. Even the Windows virus
stuff seems to have died off as of late.
Yes, there are the purists like the Qmail folks that believe that
Sendmail is fundamentally flawed. Having dealt with both, I'm still
a Sendmail fan and refuse to run Qmail because :
* The documentation is absolutely horrid to this day.
* The logging is equally as horrid, and I shouldn't need Splunk to
make heads or tails of an email transaction.
* It's arguably more difficult to configure and tweak than Sendmail
(i.e. Oh, I need double-bounce too? and Hey, so-n-so wrote a plugin
for this. It's similar to this other guy's plugin but different.)
As for Postfix, I don't recall having heard anything good or bad
about it from a security perspective. Then again, I don't have time
to read mailing lists, I blame Thunderbird for seeing your original
posting in the little pop-up window by the sys-tray ;-)
Like Qmail, it's setup to be a drop-in replacement for Sendmail
(same CLI options, etc). Most people I know that run Postfix adopted
it when Sendmail was still somewhat difficult to work with, during
the transition to using m4 exclusively and adding the submit queue.
Difficult meaning you had to read the docs fairly well before
expecting it to work. Having run an ISP, learning this was sort of a
coming of age thing.
One thing I do like about Postfix is the LDAP/SQL support, that is
very cool. If I was approached to do something along those lines and
Postfix proved to be the right tool, I'd use it in a second for that
project.
Anyway, blah blah blah. It's almost Beer:30. Happy Wednesday
everyone ;-)

Chris
