If sendmail isn't listening to anything but 127.0.0.1 - what is the
difference? No need to patch unless you ARE using it for local delivery
- in which case, the only exposure is to exploits such as ultra long
headers

I don't know what mailx is. procmail is typically a hand in hand with
sendmail. Procmail has no clue on what mail is to be received by system
and is rather simple minded.
/bin/mail functions as a send / read utility but cannot 'receive'.

I think that you will find Hans and some others like the simple
mindedness of exim. That being said, out of the box, sendmail would have
done exactly what you wanted. Little fear or need to continually
patch/update if your not exposing it to the outside world. Also, for the
record, even if you use fetchmail, you still need an MTA to process the
mail.
