Our corporation is moving off of CommuniGate Pro onto Exchange 2007, and we are looking for the wildcard alias (don't know the actualy term for it) feature.Basically we need testuser+stuff@mydomain.com, testuser+853@mydomain.com, etc to deliver mail to testuser. This has to be done on the fly without administrator intervention. We create testuser, and testuser+* works (of course if there is an EMS command to do this, thats fine...we just can't continually create new aliases).Is this even available in Exchange 2007? Is there a work around or a third party application?

I currenlty do not have a way to test this but it looks like you can setup a transportrule to perform the filtering based on FromAddressContains http://technet.microsoft.com/en-us/library/bb123927(EXCHG.80).aspx $Condition = Get-TransportRulePredicate FromAddressContains http://technet.microsoft.com/en-us/library/aa995960(EXCHG.80).aspx

Im looking at this article.http://technet.microsoft.com/en-us/library/aa997187(EXCHG.80).aspxIs there some way to Regex the conditionals?if i were to do this in perl i would just do:if($definedaddress =~ /(\w+)+\w*\d*/sm) { $actualaddress = $1;}Any way i can do that with these

Currently, Microsoft does NOT provide a way to do this. This was pretty popular at one time with small businesses or someone that wanted all mail to their domain to go to a specific address. However, you are creating a giant spam magnet that the bots will innundate. Keep that in mind. That being said, there is a company called Turbo Geeks that has a spiffy toold called MailBasket MD that is very configurable and will do pretty much what you want. I have tested it before and it does work great. http://www.turbogeeks.com/products/mailbasket.asp I checked their site and am not sure if they have an E2K7 version or not, but it might be worth checking in to.

you could also develop your own transport agent that does this for you. you could probably start with this http://www.codeplex.com/catchallagentand change the code slightly to create what you want.

Okay, so the Perl programmer wrote a C# Transport Agent (woohoo). I basically altered the above agent's re-write of the address, and it worked beautifully. You'll notice that I have some includes that aren't necessarily required. The C# Express Studio complained when I didn't have them, so I went ahead and appeased it.This work is a derivative of the work found at http://www.codeplex.com/catchallagent.

Hi All, I am new to exchange server and all . I am trying above program but I didn't understand the function parameter "SmtpServer server" of CreateAgent() function . please help me on "SmtpServer "what value should I pass to that function CreateAgent(). Thank you In advance . Pravin Thokal
