[Mailman-Users] sendmail says: Data format error

[Uwe Steinmann]

Hi,

I have installed Mailman 1.0 on a SuSE 6.2 System running sendmail 8.9.3.
There hasn't been any problems during installation.
I was able to create a new list and configure it (The name is 'ieg').

When I send a message to the list, it is archived but isn't delivered
to the members.

All it says in the logs is 'Data format error' and I don't get any
response, not even the list owner gets an error message.

Would be great if somebody with a better understanding of mail delivery
could help. I'm not even sure if this a Mailman problem though it's
first I encounter such problems.

Thanks.

  Uwe
