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 following word in the Microsoft Knowledge Base:
