Hi,

some time ago I posted that we are having trouble with emails that
should not be accepted by our server.

Finally figured that they are coming from an authenticated user.

Does anyone know how I can constrain authenticated user only to be able
to send mails with sender=theiremail via a mysql table?

Best regards

Eddy Ilg
