It is done, without bettering.

But what is the diffrence between sending with postfix using a distributor generated in plesk-email-panel and the connection of mailman to postfix ?
If it is no internal mailman issue, though a special configuration issue needed for mailman, when postfix is sending everything well, but mailman tasks.

What information could help to localize the failure ?
