Recent versions offer a gateway feature: http://docs.ipswitch.com/_Messaging/IMailServer/v12/Help/Admin/index.htm?13627.htm Prior to that, you had to use aliases... Of course, the concerns are dictionary attacks if your gateway does NOT have a list of valid email addresses to be able to drop connections on attackers. (There are scripts that will poll the Exchange Server using LDAP twice an hour to obtain a list of valid email addresses to validate against - this is how I use ORF to front-end Exchange Servers) -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Carl Wagar Sent: Tuesday, July 02, 2013 12:53 PM To: [email protected] Subject: [MBF]Re: anti-spam solutions for ms-exchange Ok thanks for the hint. I would have thought I could just relay the whole domain (rather than setting up mailboxes?), after filtering is applied (assuming I set up the MX record in the DNS to point to the imail server with say, priority 10 and the real server with priority 15 ?) and then have Imail forward all messages for that domain to the exchange server, presumably after declude/sniffer runs. Will look into it. Thanks. Carl ############################################################# This message is sent to you because you are subscribed to the mailing list <[email protected]>.
