Sorry for mixing this up.. the default configuration (and that on S)
contains delay_after_cutoff=true, but Renaud Allard uses
delay_after_cutoff=false.
Consensus is, that delay_after_cutoff=false and version < 4.64
(or >=4.66 with patch) should avoid this problem?

What about putting delay_after_cutoff=false (sufficently commented)
into the default configuration? In the time of greylisting etc.
it may be better to risk more traffic than "loosing mail".
