[PATCH] send-email: have default batch size when relogin delay is given

[Stefan Beller <sbeller@google.com>]

When the batch size is neither configured nor given on the command
line, but the relogin delay is given, then the user is not using the
the feature as intended. But as the user gave a relogin delay, there is
clearly the intention to delay sending out emails. Assume a batch size
of 1 instead of silently ignoring the given relogin delay.
