Smail 3.1 has a setup to do BSMTP over uucp.  Basically is is just a
configuration option that writes SMTP output to files without the HELO
line.  Then you run a shell script periodically to add the HELO and
all the messages and pipe through compress and uux to the remote site.
You can use either the uucp or SMTP addressing forms - the receiving
smail will treat them identically anyway.  There's also an unbatched
SMTP over uucp that would still take 2 files per message but allows
unlimited recipients of a single copy, which would be good for anyone
running a list exploder.  Batching would be a real win for anyone
using PEP modems though - it should eliminate the line-turnaround
time for all those X files.
