Grey Listing, whats a reasonable defer time ?

I employed GreyListing at the weekend, and went with the default defer time of 10 minutes. Looking in the logs this morning, I can see a number of emails which have been deferred, but the 10 minute deferral time has well exceeded this. Two of my web sites are mail order companies with strict cut off times for recieving orders. So they can't really afford to be waiting for an email for more than 15 minutes. I appreciate that the retry would be on the senders email server, so there's nothing I can do to speed this up. But what about lowering the deferral at my end, what would be a reasonable time without stalling email transport. Also, would changing the "Resend Acceptance Period" to a lower number help. These companies rely heavily on meeting customer deadlines. Anything to reduce spam is a bonus, but not at the expense of upsetting an urgent customer delivery.

  Do you see any email in the GreyListing Report that indicates emails to them are being flagged?

  I'm not sure to be honest. I can see in the report emails being deferred. Until i can be sure that nothing is being delayed too much, I've disabled it, so the report below may be relected in that. never spotted that upload button.

  edited Assuming that sales@ email shown is the email you're concerned with, you can disable GreyListing for that domain if you wish.

  I guess until GreyListing has had a half decent chance to build it's own database, there are bound to be some delays. Which then takes me back to my original question. What would be considered a reasonable or the bare minumum defer time. If the idea of GreyListing is because spammers don't retry, then could the defer be dropped to the lowest possible defer time.

  Hello :) It won't deliver the message faster because, as you mentioned, you don't control the retry configuration on the sending server. Lowering the "Initial Deferral Period (in minutes)" value to 5 minutes won't speed up mail delivery unless the sending server has a five minute retry time. Lowering the "Resend Acceptance Period" value would actually make it harder for senders with higher retry configurations to have their email accepted. Thank you.
