-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi there.
We have a couple of servers handling thousands of messages a day. We noticed that some of our users will use their autheticated account to send messages from other valid accounts not sitting in our servers. By using smtpd_reject_unlisted_sender = yes we solve the problem partially by not letting users to use an incorrect local email account to send messages. However, is there a way to prevent local authenticated users sending email with valid hotmail or gmail accounts through our smtp servers? We cannot use reject_authenticated_sender_login_mismatch since some of our business customers have their own intranet email servers doing smtp authenticated relays. Thanks in advance Ignacio -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iEYEARECAAYFAkon7acACgkQoYMx3fsuWuoxvACgnXEfqVxTvTcyEmMbBlVAgio9 t6sAoJnkq42Rmf9RhxDJyTJXYfvpk39d =Wuhm -----END PGP SIGNATURE-----
