Thanks for your response :
I've put in main.cf :
smtpd_helo_required = yes
smtpd_recipient_restrictions = reject_unknown_recipient_domain
reject_unauth_destination

Hi all,
my mail server provides an stmp access. I thought I've configured it to
deny relay. It is true when I try basically to send a mail to another
domain. But some persons seem to bypass this policy using themself a
relay domain ::
24BDEE7918: to=<donna@xxxxxxxxxxxxxx>,
relay=smtp1.msp.securence.com[216.17.3.48]:25, delay=3.3,
delays=0.02/0.01/1.2/2.1, dsn=2.0.0, status=sent (250 OK, queued as
<20070429143657.24BDEE7918@
How can I deny these mails, and deny use of another relay ?
It would help if you told us how you have configured it at the moment.
What have you done to prevent unauthorised relaying?
output from "postconf -n" will help enormously.
Regards
Stuart
