X400: X400GATE.EXE Hangs on 74+ Characters in Subject Line (115446)

SYMPTOMS

The X400GATE.EXE hangs when too many characters (74 or more) are in the subject line of the outgoing message. The same message coming into the system does not hang the gateway.

The gateway logs the messages before hanging with these errors (notice the negative byte count):

Extracting message from local message store: 0000xxxx
ERROR 3 (creating PO1 originator address): Malformed address: type <0>
ERROR 3 (converting PC mail message to X.400): No Originator Found
ERROR 3 (converting PC mail message to X.400): Local from to x400 con...

Pointer count: 256; byte count: -117212

Note: the SUBJECT length for this example was 170 characters.

This hotfix has been posted to the following Internet location as X400gy2k.exe:

ftp://ftp.microsoft.com/bussys/mail/gateways-public/All-Y2K/

WORKAROUND

This affects messages coming in from Profs that you reply to. They come in fine but hang the gateway once you reply to them. If you forward the message it also works fine and does not hang the gateway.

STATUS

Microsoft has confirmed this to be a problem in Microsoft Mail Gateway to X.400 version 3.2.

STEPS TO REPRODUCE BEHAVIOR

Set up the X.400 gateway.
Create a message in the Windows client. (MS-DOS handles the subject differently and does not hang the gateway.) Send the message to an X.400 user.
Run the gateway. Notice that the gateway PC hangs when it tries to send the message.
