The addition of "nobody" to the alias ensures that "grpname-outgoing"
doesn't appear in the message header, but you should examine a header to
make sure it's working. If not, check how you have the aliase set up, or
post all your aliases for "grpname" here so we can see them.

Assuming you are using sendmail as the MTA, put something like this in
your virtusertable:
grpname-outgoing@domain.tld error:nouser User unknown
Substitute the actual listname and domain name, of course. Sendmail will
then reject mail addressed to grpname-outgoing, but this will not stop the
alias from working for resend.
