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. > >> The poor souls sitting behind dodgy or over-zealous greylisters, otherwise >> unreliable servers- noen of which you can 'fix' from your end - >> self-Identify to >> their correspondents, (and no others).

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