Re: Virtusertable Entry Failure

Just to cover the basics, I am sure you rebuilt the db after editing 
the virtusertable file right?  ;-)

The suggestion to see what the log shows is a good one.  You could 
even set the debug level to 9, restart sendmail and try sending a 
message to the list and checking the maillog, and then reset the 
debug back to whatever it was beforehand...
