Sendmail is the most widely used MTA on the internet (>60%), when 
vulnerabilities have been discovered in the past they were fixed very 
quickly.
Not sure where you get the concept "  *Still* a bad idea", its the MTA 
of choice in my book and has been for over 10 years and facing it on the 
internet correctly configured has never been a bad idea...

Sendmail is over 25 years old and is still the number 1, its the most 
configurable and provides the best functionality....

A lot of sys admins are cautious of it because they don't know how it 
works well enough... but its like anything these days once you know how 
to use it, its very simple to make it do what you want...

Other good choices include Exim, which scales very well for very very 
large enterprises with 100,000's of users.
