MDeferred: 450 <anybody(_at_)world(_dot_)de>: Recipient address rejected:

With this error, you should retry to send the message within the
300 Seconds, which mean, if you send an (unverified) message, the
receiving host reject it and after 300 Seconds it is bounced.


Icko.  That's an uber-lame way to do it -- for one, no MTA (that  
I'm aware of) parses the message and grabs a delay and resends, and  
two, a default resend in Sendmail (out of the box install) is 15  
minutes - 900 seconds, meaning that the message will be retried  
AFTER 900 seconds.  Generally.

If it's working the way you say, then the particular recipient  
mailhost generating that greylisting message is too fscking  
braindead to receive email.

No, Michelle is wrong.  the greylist message means exactly waht it  
says, the delivery is delayed for 300 seconds.  Any retries in less  
than 300 seconds are ignored.  After 300 seconds, the message is  
accepted.
