Hi everybody.
I've some communication problem between sendmail and IMailServer.
Some customer use sendmail as SMTP server to send e-mail to our accounts.
Each time the destination user is unknown the sendmail process send a "Bad
mail" message
to our IMailServer but with a "Null Sender" instead of the original sender
(the customer e-mail address)
so as "Refuse NULL Sender" is checked, the bad mail never reach our
domain...
Do you know how to proceed in order to fix this ? (maybe some setting up on
sendmail ?)
Thanks.
Jean-Michel.
