Exchange 2003 Relay Restrictions

Last Modified: 2016-01-27
Hello All,

Simple question... Ran into some issues getting flagged as SPAM and went thru all the steps to make sure OPEN relay was not on...  Only The list below for Ip is chosen and all i have is a couple servers i need... Also I unchecked Allow all computers etc.... However I notice that on the USERS tab in that section It has Submit and Relay allow to All Authenticated Users.... Can this be the problem? I expect this means that if someone internally gets infected with a domain account they can then relay as well? can I remove this completely and have the users emtpy or will this cause problems?  I notice sometimes when i look at the IMAP4 and SMTP current sessions i see a couple random connections that have nothing to do with us... Thanks for the help.
