Well - I DID see that earlier today myself.
But only 'coz Dominion Virginia power had an outage of over an hour and there is
no UPS on my cable modem.
Otherwise, Exim rarely gets into the third or fourth second of wall-clock time,
on any given submission - even with a 2,000+ line configuration file full of SQL
calls.
With an MUA (SeaMonkey) set to bang on Dovecot every 60 secnds, yet. Which is
wot first sees the link has gone away.
A decent MUA, after all, is *supposed to* allow for the same general time-outs
as any other smtp 'player'. Closer to 4 minutes than 4 seconds.
