Hi Chris, Can't you just configure an administrator address in the IIS SMTP service? That's what I always do.

Currently, this box is running GFI mail essentials and Mail Security (in gateway mode) with Exchange 5.5. Though everything is working well, I have one small glitch. It seems that bounce backs from the SMTP Mail Relay server replies to emails that trigger rules as Administrator@nc10s069. I have setup a 'masquerade domain' (IIS V6.0 feature) of GlobalKnowledge.com in hopes that it will reply as Administrator@xxxxxxxxxxxxxxxxxxx instead. After contacting GFI, they stated that they have not tested their products on a Gateway box running Windows 2003 IISV6.0 even though they say their product supports this OS. Any clue on what may be going on here? Their support said that I would have to use some tool called 'Meta Edit' or 'ADSI' to change this address, although they could not support me in doing this. I am pleased with their product but kind of dissapointed in their support for a product that their software is advertised to work on. They also said that these tools could 'damage' the machine, 'so be careful.' No help for me.... Thanks for your ideas, Chris Wall ASSC Exchange Administrator ------------------------------------------------------ List Archives: http://www.webelists.com/cgi/lyris.pl?enter=exchangelist Exchange Newsletters: http://www.msexchange.org/pages/newsletter.asp Exchange FAQ: http://www.msexchange.org/pages/larticle.asp?type=FAQ ------------------------------------------------------ Other Internet Software Marketing Sites: Leading Network Software Directory: http://www.serverfiles.com No.1 ISA Server Resource Site: http://www.isaserver.org Windows Security Resource Site: http://www.windowsecurity.com/ Network Security Library: http://www.secinf.net/ Windows 2000/NT Fax Solutions: http://www.ntfaxfaq.com ------------------------------------------------------ You are currently subscribed to this MSExchange.org Discussion List as: tshinder@xxxxxxxxxxxxxxxxxx To unsubscribe send a blank email to $subst('Email.Unsub')
