SYMPTOMS
Messages that are received into Microsoft Exchange via the Microsoft Mail Connector and have X.400 addresses in the From field may contain non- printable characters and may not be deliverable by other mail systems.



CAUSE
The Microsoft Mail Connector converts incoming messages that contain Escape Sequences ('//', '$/', and so on) in the DDA.VALUE to non-printable characters and does not convert them to the proper characters ('/') before passing the messages into Microsoft Exchange.



STATUS
Microsoft has confirmed this to be a problem in Microsoft Exchange Server version 5.0. This problem has been corrected in the latest U.S. Service Pack for Microsoft Exchange Server version 5.0. For information on obtaining the Service Pack, query on the following word in the Microsoft Knowledge Base (without the spaces):

MORE INFORMATION
X.400 addresses that have a DDA.VALUE of a Microsoft Mail address (net/po/alias) (or any other field that contains a '/' character) will need to Escape the '/' character with either '$' or '/' if the delimiter between fields is a '/' character.

These Escaped characters (and the following '/') are converted to a non- printable character so that they are not mistaken for a delimiter during the separation process of the address. After this is done, the non- printable character is replaced with a single '/' because the delimiter has been changed to a ';'.

An example of this is:   /c=us/a=mci/p=microsoft/o=pss/dda.type=ms/dda.value=microsoft$/pss$/mail box

to

  /c=us/a=mci/p=microsoft/o=pss/dda.type=ms/dda.value=microsoft[171]pss[17 1]mailbox

to

  c=us;a=mci;p=microsoft;o=pss;dda:ms=microsoft/pss/mailbox
