[Mailman-Users] Postfix/Cyrus/Mailman-2.1.8: data format error..: Mailbox does not exist

[Peo Nathan]

Hi,

I have installed Mailman 2.1.8 on a box running postfix and cyrus email working. But, emails to mailman aliases are all bouncing back with data format error..: Mailbox does not exist.

For example, even the subscription request bounces back a follows. Any suggestions or help would be greatly appreciated.
