And don't forget that the sender might not be online 24/7 either --
and worst case, the sender and receiver might never be online at the
same time. The SMTP approach is threefold:

   (a) if you're not online long enough to retry regularly yourself,
send your email via your ISP's smarthost, which is online all the
time, can cope with lots of mail going through it, and trusts you
enough to forward your email
   (b) have secondary MXes, which accept your mail and forward it to
you when you're back online
   (c) have IMAP, POP, BSMTP, UUCP, etc to let your mail spool
somewhere that's online 24/7 and can be batch downloaded fairly
quickly when you're online

Since we want freedom boxes to be a fully fledged internet hosts,
having alternative things like IMAP and POP probably isn't the ideal
solution, but smarthosts/secondaries and maybe taking some hints from
UUCP (if two boxes aren't directly addressable, but can reach each
other indirectly via intermediate hosts) is probably pretty feasible.
