[Mailman-Users] Exim / Mailman No Longer Working

[Ben Cummings]

Hello,

I am having some difficulty getting Mailman to work with Exim after a
recent upgrade of the email software that we run. The configuration for
exim has remained, as has the configuration for mailman. This *was*
working, but is not after the update.

The error message i get in the Exim log:

I'm sure i'm missing something really simple....but i just can't see
what it is...

Any help would be much appreciated.
