Exchange 2003 Server with a Domain of 35 Users+ -My Server is not an open relay -I have Successful authentication checked under Virtual SMTP Server -I have Filter Recipients checked under Recipient Filtering in Message Delivery
Symantec Endpoint Protection 11.0 with the latest build. All users have the most recent virus definitions. Found a few viruses lately, but all seems to be fine client side. There is only one Virtual SMTP connector and that is on the Exchange server.
Started out being blacklisted on SpamCop and has moved to about 8 others (but not Spamcop any more) according to mxtoolbox.
Ran Exchange BPA. -Stated I failed an Open Relay test -Error says SMTP instance failed open relay test. Restrictions are in place but the workstation or user running this tool is capable of using the open relay.........
On the Exchange queue I have multiple domains from postmaster@mydomain.com
