My thanks, also, to Bruce and others who do likewise.  Even a document
number helps.

Actually, it's intact as served by bama.ua.edu.  So your MUA, any intervening
MTAs (poor Charlie), and LISTSERV are friendly to it.  No representations

Why do they do that?  From RFC 821:

      4.5.3.  SIZES

         There are several objects that have required minimum maximum
         sizes.  That is, every implementation must be able to receive
         objects of at least these sizes, but must not send objects
         larger than these sizes.
             [ ...]

            text line

               The maximum total length of a text line including the
               <CRLF> is 1000 characters (but not counting the leading
               dot duplicated for transparency).

Here, though, IBM shares the blame.  The VM/CMS implementation of SMTP
(optionally) used virtual readers and punches as a Mail vehicle, thus
enforcing (in violation of RFC 821) an 82-character limit.

Which isn't the same.  Perhaps:

Amen.

Unless the resource costs of bandwidth, contention, and latency
are deemed inconsequential.

Vive la Bookie!  A bas PDF.  Please, IBM, don't switch.
