No, I don't think there was an actual patch. In the mailing-list
the subject of RTN must have a top 10 spot in the 'HylaFAX Review
of the Year', but most relevant is a thread between Robert Coluqhoun
and David Wolley around the 4 Aug 98. 

Then, on the 11 Aug 98, David Weiss said :

Further info from David enabled Robert to come up with the tagline 
patch, which *may* reduce the incidence of RTN responses on the first
page, but doesn't alter transmission rates, etc.

Hope this is of some help,
