Really?  Because nowadays, there's all this extra crap that didn't used
to exist.

Now you need to sign your mail with DKIM, have SPF records, and even if
you cross all the T's and dot all the I's, you can expect your mail to be
rejected at some major mail sites because the LACK of a consistent high
volume of mail being sent by your site is actually scored against you. 
On the inbound side, you now need to be filtering your mail with 
Spamassassin and DNSBL's, and also virus scanners because it's likely
some of your users won't be.  You need to support both IMAP _and_ webmail
if you want to be able to support users, because we are now in that
"post-PC" era where people expect to be able to sit down at an arbitrary
PC and have an experience on par with that of any of the mail service

I've watched in dismay as many technically competent sysadmins, and even
whole service providers, have given up and outsourced e-mail, because
it is so difficult to do well.  Even Apple finally ditched their
OSX Server product's email services, which had for years been one of
my best examples of "it's still possible to run this yourself."

If this is your idea of "hasn't gotten much more complicated", I salute
your technical prowess.  It's not that I want this to be the status quo,
but I'm also not so blind as to deny what is going on.  :-(
