Just as a follow up.. my (mis) understanding (delete as applicable) 'Allow all computers which successfully authenticate to relay, regardless of the list above'
Allows computers that meet authentication requirements set in the Authentication dialog box to relay messages to the SMTP virtual server. Which would mean a virtual server enabled for anonymous authentication can be potentially used as a relay server because it is 'authenticated' ??? Cheers Mylo -----Original Message----- From: Myles, Damian Sent: 23 April 2002 11:58 To: Exchange Discussions Subject: Ex2K SMTP Settings Hi, Can anyone clarify whether the 'Allow all computers which successfully authenticate to relay, regardless of the list above' checkbox on an SMTP Virtual Server would define a logged-on user (AD), telnetting to Port 25 of the Exchange Server as being 'authenticated'. Our test environment is down at the moment so I can't test this out. Essentially, we're looking to secure our servers internally from mail spoofing, by using the tying down Connection Control and Relay Restrictions on the SMTP service to grant access to 'Only the list below', i.e. Exchange Servers only. Just need to know what 'authenticated' means in this context.
