A 29 minute grey list!? Are the people using this server really ok with a minimum 30 minute delay in getting their mail?
Given that mail zombie's usually only try once for each email address, I have mine set to 30 seconds.
Granted, the bots are getting more sophisticated and sometimes try more often but it's still effective.
