I am intrigued by your mention of using filter_recipient. I did a
grep on that and can't find it. Is that part of mimedefang?
Thanks for everyone's help. I was able to get it to work. I already
could make it work with access table, but this method does not produce
rejection notices. The undocumented exclamation point is the key.
How I did it:
I added define(`_VIRTUSER_STOP_ONE_LEVEL_RECURSION_')dnl to
sendmail.mc as a precaution. Everything worked without it.
