I'm not sure about the x.400 spec, but if you are upgrading from 5.5 to 2000 then you are correct. Since 2000 requires Active Directory, AD follows the standard BIND DNS naming conventions. It only allows letters, numbers or a hyphen. An underscore is allowed in a NetBIOS naming convention, but not in AD.
This info is found in RFC952 in the Lexical Grammar section (I had this info on file from a customer site and it was not the easiest documentation to find!). -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of [EMAIL PROTECTED] Sent: Wednesday, March 12, 2003 10:01 PM To: Exchange Discussions Subject: x.400 name Does anyone know of any issues with an x.400 address that contains an underscore. It looks like the x.400 generator puts a "?" for the underscore, but is this a problem. I am working on a system that is upgrading from exchange 5.5, 3 sites, connected with site connectors. We are unsure if some of the unknown mail routing issues are a result of this underscore in the ORG name that is in the x.400 address. _________________________________________________________________ List posting FAQ: http://www.swinc.com/resource/exch_faq.htm Archives: http://www.swynk.com/sitesearch/search.asp To unsubscribe: mailto:[EMAIL PROTECTED] Exchange List admin: [EMAIL PROTECTED] _________________________________________________________________ List posting FAQ: http://www.swinc.com/resource/exch_faq.htm Archives: http://www.swynk.com/sitesearch/search.asp To unsubscribe: mailto:[EMAIL PROTECTED] Exchange List admin: [EMAIL PROTECTED]
