For the simple case like this you can get away with:

   masquerade_domains = syslang.net

and if you want to get fancy:

   masquerade_classes = envelope_sender, envelope_recipient,  
header_sender, header_recipient

and possibly:

   masquerade_exceptions = root

For more complex stuff there's a 'virtual' table that has all kinds  
of other rules.

For some reason the problems I seem to run into seem to do not have  
an .mc macro defined. :(   Sometimes I can find a hint online, but  
the community seems to be sparse.

Try searching on how to change the hostname sendmail sends for HELO  
greeting (no peeking below).  It took me what I thought was too long,  
like a few hours to find it.  Maybe I was having a Bad Google Day, I  
dunno.  For the archives:
