sendmail woes

[Matthew Carpenter]

One language too much, yes...  I use the mc/m4 files located in
/usr/share/sendmail to do most of my sendmail.cf configuration.  It takes
a little learning, but you take a mc file and an m4 file and use the m4
utility to generate the .cf file....  unfortunately, I don't know the mc
code behind the sendmail.cf patches listed below.
If I'm not mistaken they are basically just to hack out the servername
from the to: field for the recipient.
