There's a function to wrap and shorten references:

| message-shorten-references is a compiled Lisp function in `message'.
| (message-shorten-references HEADER REFERENCES)
| 
| Trim REFERENCES to be 21 Message-ID long or less, and fold them.
| When sending via news, also check that the REFERENCES are less
| than 988 characters long, and if they are not, trim them until
| they are.

The code mentions broken INN versions (not everything that's broken is
Outlook).  As in NNTP, there's the SMTP line limit.

Surely there has to be a Perl module which already deals with the
nitty-gritty details.
