XADM: NDR's Due to Non-Printable Characters in the DDA Value (156707)
The information in this article applies to:
- Microsoft Exchange Server 4.0
This article was previously published under Q156707 SYMPTOMS
When a message is received by Microsoft Exchange and the sender's
address contains a DDA Value, characters within the string might be
translated by Microsoft Exchange. This can cause the originating system
to refuse to accept replies to the sender.
CAUSE
The only characters allowed in the ORName address DomainDefinedAttribute
are printable characters. However, Microsoft Exchange translates
character sequences used to indicate special characters in DDA values
and sends these non-printable characters to other email systems. For
example: the character string (b) is translated to ! and the character
string (a) is translated to @.
STATUS
Microsoft has confirmed this to be a problem in Microsoft Exchange Server
version 4.0. This problem was corrected in the latest Microsoft Exchange
Service Pack. For information on obtaining the Service Pack, query on the
