SYMPTOMS

Custom recipients created to allow addressing to SNADS recipients fail, because the custom recipient address does not match after the conversion from Internet to X.400 mail.

CAUSE

The conversion of the RFC822 address attributes to X.400 attributes mistakenly leaves the "at" sign (@) in the address. Because this is not a printable character in X.400, the address does not match the custom recipient address, and the message is returned as non-deliverable. The FROM field of the message displays as an X.400 address with a DDA value when a custom recipient exists in the site.

STATUS

Microsoft has confirmed this to be a problem in Microsoft Exchange Server, versions 4.0 and 5.0. This problem was corrected in the latest Microsoft Exchange Server 4.0 and 5.0 U.S. Service Packs.

MORE INFORMATION

The incoming message's address was converted from RFC822 format to an X.400 OR Name using the RFC1327's printable string conversions:

        ps-encoded       = *( ps-restricted-char / ps-encoded-char )
        ps-encoded-char  =                   "(a)"               ; (@)
                                           / "(p)"               ; (%)
                                           / "(b)"               ; (!)
                                           / "(q)"               ; (")
                                           / "(u)"               ; (_)
                                           / "(l)"               ; "("
                                           / "(r)"               ; ")"
                                           / "(" 3DIGIT ")"

The DDA Type is "RFC-822" and the address is the escape equivalent version of the RFC822 address.
