Sendmail choked on the message.

If RT can send any mail at all successfully, then the most likely cause of 
this particular problem is a broken email address for one of the recipients. 
The '-t' flag that RT is passing to sendmail tells it to scan the headers 
for recipients. If sendmail sees an improper email address (such as one 
containing a non-ASCII character) in a To/Cc/Bcc header, it will reject the 
message altogether. I do not know for sure, but I'd bet that RT is less 
strict in what it allows as a user email address than sendmail is.
