Why don't you use the sendmail features define(`confSEPARATE_PROC',
`true') define(`confTO_QUEUERETURN', `1d') which prevent 1 email to hold
the rest of the queue down (confSEPARATE_PROC) and try for a day to
deliver the mail (confTO_QUEUERETURN)?

You can also use multiple sendmail spool dirs, with separate
queuerunners. Email that cannot be delivered within the hour is moved to
the next spool, where the queuerunner only runs every hour After 4 hours
is is moved to the next one with a runner which checks every 4 hours,

Cheers, Johan
