SYMPTOMS
Recipient addresses on messages sent through an EDK (Exchange Development Kit) gateway are corrupted. As a result, the message cannot be delivered to the recipient. This occurs if the address is in the form:
FAX:username@(xxx)xxxxxxx
where (xxx)xxxxxxx is a phone number with an area code in parentheses that starts with a 0, 1, or 2. Also, where FAX is the address type defined by the EDK gateway. The recipient name is corrupted to:
FAX:username@E9368080
The corruption, in this case the letter E, is different depending on the areacode provided.
CAUSE
The use of parentheses in the address triggers the corruption. Parentheses are used in an X.400 address to portray characters such as the at sign (@), the exclamation mark (!), or the percent sign (%) in an address. The area code of this fax address is incorrectly interpreted as a non-printable string of characters. This occurs for any three digits enclosed in parentheses, where the first digit is a 0, 1, or 2.
RESOLUTION
To resolve this problem, obtain the latest service pack for Exchange Server version 5.5. For additional information, click the following article number to view the article in the Microsoft Knowledge Base:

STATUS
Microsoft has confirmed this to be a problem in Exchange Server version 5.5. This problem was first corrected in Exchange Server 5.5 Service Pack 3.
MORE INFORMATION
Exchange Server uses RFC 987 to interpret parentheses in an address. RFC 987 provides a method of mapping non-printable characters to printable ones for a legal X.400 address. Most X.400 address attributes have to be printable characters as defined in Table 4 of Recommendation X.409. For example, RFC 987 specifies the following:
Non-Printable Characters X.400 Printable Characters
@ (a)
% (p)
! (b)
" (q)
_ (u)
3digits 3digits
Exchange Server implements RFC 987 in Escprint.dll. The fixed files for this issue add implementation for a more recent RFC that obsoletes RFC. The current RFC is RFC 2156.
