I suppose I can't speak for everyone, but in this century if my computer 
  couldn't complete a mail delivery within the several-day default 
sendmail timeout, I probably wouldn't choose it to run as an internet 
mail server.  In a previous century I did run mail servers over dialups, 
but I used uucp which is designed for that as the transport and deals 
with the batching and timing accordingly.
