[Mailman-Users] Exim4... sorry to ask...

[James Nightly]

I have routes and transport setup in Exim4. Its driving me crazy. I
keep getting the same rejected RCPT Unrouteable address and I don't
know why.

exim4 -bt mailman at lists.myschool.org
R: system_aliases for mailman at lists.myschool.org
mailman at lists.myschool.org is undeliverable: Unrouteable address

Any tips or suggestions where to look, I've been at it for days now...
