The mailing list for listmasters using Sympa

[<address@concealed>]

Hello,

i´m running  Sympa 5.1.2 . The relevant list is configured as "newsletter", so
that only moderators can post. If somebody else tries to post to the message
will be rejectet and send back to the sender(with the complete mailbody).

If the message was spam and the sender is faked, somebody who recives the
rejectet mail could arrive at the conclusion that my Smpa installation is used
to deliver spam an blacklists my server.

Is it possible to configure Sympa in a way, that a mail is rejectet only with
"user unkown" without the original body?

best rerards
