Here is what the mailman/logs.smtp-failures log had:

May 13 21:15:31 1999 TrySMTPDelivery: To ['jnlewis@arachnerd.com']: May 13 21:15:31 1999 TrySMTPDelivery: Mailman.pythonlib.smtplib.SMTPRecipientsRefused / jnlewis@arachnerd.com: <jnlewis@arachnerd.com>... Relaying denied (dequeued) May 13 21:15:33 1999 TrySMTPDelivery: To ['john_lewis@woodberry.org']: May 13 21:15:33 1999 TrySMTPDelivery: Mailman.pythonlib.smtplib.SMTPRecipientsRefused / john_lewis@woodberry.org: <john_lewis@woodberry.org>... Relaying denied (dequeued)

So clearly its a sendmail problem, but how? Is it yet another smrsh problem? Where do I look to resolve this?

help!
