I am geeting below given error message while sending mail to "email@example.com,
SMTP error from remote mail server after end of data:
host mail3.transition-asia.com [184.108.40.206]:
550 Denied by policy
Can anyone tell me that how to resolved this and how to delist the mail server IP repolation..
If you have McAfee Enterprise version then the solution is in this article -
When the option Or if recipient is not listed in LDAP is enabled under the recipient Check option of Email recipient authentication in Email and Web Security Appliance software, you see outbound emails blocked with the error code:
550 - Denied by policy.
Enabling recipient check Or if recipient is not listed in LDAP by default applies the check as a global policy. Ensure you apply this recipient check only for incoming SMTP traffic.
- The full details of how to do this are given immediately after that advice.Message was edited by: Hayton on 11/12/13 06:47:18 GMT
your internal mail server falling in Authentication\RBL so no need to worry simply create on group and create new mail policy for only your internal mail server and disabled sender authentication disabled for only outbound mail traffic for this group .
