I've moved in the past 6 months into my first home - after nearly 60 years of 
living as a renter, I'm now dealing with all the viccisitudes of home 
ownership. Since I posted my problem, we had a pretty nasty cold front move 
in to my area, and I've been dealing with multiple problems having to do with 
containing heat in a structure that was built over 40 years before I was 
born, so I haven't had much time to work on this. 

What's puzzling to me is that the configuration I'd been using no longer 
works. I tried editing the sendmail configuration file, but I'm not sure I 
did it correctly - those entries weren't so self evident. For example, the 
line that was suggested be edited by someone looks like this:

dnl # Uncomment and edit the following line if your outgoing mail needs to
dnl # be sent out through an external mail server:
dnl #
dnl define(`SMART_HOST', `smtp.your.provider')dnl

First, I don't understand what those 'dnl' acronyms stand for
Secondly, it seems to be saying to uncomment a line that's already uncommented
Third, I did try putting my provider in place of the 'smtp.your.provider' but 
that didn't accomplish anything

More puzzling to me is that denyhosts is working - it sends out an email each 
time it blacklists a host that's trying to log on to my system via ssh, and 
I'm getting those just fine

But, that's as far as I've been able to get - still working on it.
