It's the age we live in. smtp no longer seen as an alternative to TWIX/TELEX, or
snail mail. Rather more phone, fax, SMS et al.
IOW - short interval is what today's 'consumer' logically expects / prefers.
WTH - snail mail and courier can be much faster than 3 or 4 day smtp 'fail', and
most have online incremental tracking number updates.
As to why I drop the attempt not just report (periodicaly) with delay_warning ..
it is 'probable' that the sender of yesterday's fail will want to send a
DIFFERENT message today in the light of the fail.
Or send by another means AND NOT have the delayed message showing up as a
complication later.

Fair question - but one for others - I no longer have enough traffic that fails
on first attempt to generate useful stats.
