Hello, Yes it does. Your mail essentials SMTP server will answer on port 25, do any processing you have defined, such as spam filtering or antivirus scanning, and then send the mail to the Exchange Server's SMTP on the alternate port you have defined. It will also let you use the pop downloader and again it will forward the mail on to the Exchange Server running on the alternate port. I have used Mail essentials for 3 years set up like this on an exchange 5.5 server.

Look up: http://support.microsoft.com/default.aspx?scid=kb;en-us;173903 This allows you to use GFI Mail essentials on port 25. You then have to configure mail essentials to use the new port that you decided on for exchange. Bill -----Original Message----- From: Gene O'Brien [mailto:Gene@xxxxxxxxxx] Sent: Tuesday, April 08, 2003 2:50 PM To: [ExchangeList] Subject: [exchangelist] Question on MX Records http://www.MSExchange.org/ Hi All, I'm setting up GFI Mail Essentials for use with our Exchange 5.5 server. This cannot be on the same server unless you're using Exchange 2000, so i'm installing it on our Web Server machine (I don't have the budget to put up a new server, and this should serve the purpose). Our DNS's MX record currently points to mail.tcr-ny.com (the domain is tcr-ny.com) I guess I need to change that to the web server (and leave mail.tcr-ny.com as the fallback), right? Would I have the entry just read something like this: tcr-ny.com mail exchanger = 10 www.tcr-ny.com tcr-ny.com mail exchanger = 20 mail.tcr-ny.com ?? Anyone have any help on this? I'm new to messing with MX records!
