I'd just configure a retry time of something large if you're worried |
13 |
about it. IIRC the default is one day and you could raise it to two days |
14 |
on a slow system without worrying that the db is getting too large. |

On the other hand it might be interesting to return an email like this: |

|
18 |
"Hi I'm the greylisting policy server. It took your mail system 36 hours |
19 |
to retry. Is your email admin insane? Almost every email server in |
20 |
existence has reasonable defaults that your idiot decided to mess with. |
21 |
I highly recommend someone take a walk down to his cube and give them a |
22 |
good smack in the back of the head." |
