[Mailman-Users] relaying denied addendum (logs/smtp-failures output)

[John Lewis]

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

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