I forgot: I read "Timeout of retry data" (32.7 in 4.50 spec). The last
transaction concerning dom.ain is logged slightly less than 7 days
earlier (the default value of retry_data_expire), so this problem
may only exist for time differences between messages to this
domain (user?) within a certain interval.
But this is "not acceptable" nonetheless...

Maybe one should use a special retry rule for rcpt_451 ?

(On the specific system S, sole retry rule matching dom.ain is
*                            *           F,2h,15m; G,16h,2h,1.5; F,4d,8h
)
