Can't send mail to some "dotted" .mil/.gov addresses with Exchange 2007 - error "#550 5.1.3 STOREDRV.Submit; invalid recipient address #SMTP#"
The error in title is returned with an NDR for SOME outgoing emails sent through Exchange 2007 to an address with a dot in the username part of the email address. The server doesn't reject the "dotted" addresses all the time. I just sent a test to "dot.dot@example-outside.c

Can you post the bounced message?
Do you have GFI MailSecurity installed on this server

No GFI and currently no Exchange-integrated AV. This is running on an SBS 2008, but I hear this happened to non-SBS. Additional note - the public domain for the organization is HIDDEN.us, but again, I've heard this happened to another EX2007 that was sending from a .com

Logs looked just like the NDR with no other info. Another user is able to successfully send to the same failed recipient. The user has tried the following:
1. delete the failing recipient from Contacts
2. delete from auto-complete (stored in the "nickname file" outlookprofilename.NK2)
3. manually type every letter of the recipient address
So far no NDR.
Points for being the only responder. Thanks!
