Hi

At times our mail server gets bombarded with 1000+ spam emails from the same
recipient (well a fake hotmail address). Surely there must be a rule that
go's like this

 if someone tried to spam mailboxes on the server more that 30 per minute
then they will get blocked for 24 hours

or even better

 if anyone tried to send more that 30 emails per minute for 5 consecutive
minutes they will get blocked for 7 days

I suppose the times could be adjusted



or something like that?

Kind Regards
