You will need to have the bounce handling and FBL functionality working in Hurricane, but you will not have to write plugins to handle the events. The suppression lists get built by the bounce handling and FBL systems inside of Hurricane MTA.

Sounds great !
As I read it this will function even though we if you don't use any of the bounce-handling or FBL functions in Hurricane – correct?

Tanks John. I've opened the support ticket, and I'm looking forward to getting this new logic in place

No problem with the questions, that is what we are here for. There is a special file deliverstatuscodes.list that you can create in your config directory to specify similar logic for failures. It is based on regular expressions. If you want to set that up, please open a support ticket as I don't personally know the format for that file, but support does.

Sorry to keep asking questions but…

This extra logic you added in… is that only for Suppression lists? or is it also used in the classification of permanent-fails?

If I were writing a plugin for handling my failures, and I said: “unsubscribe anything that permanent-fails”… would I be unsubscribing too many people?

You are right, so we have had to add some rules to exclude some things from the suppression lists. We are expanding that functionality as we speak. So for example if we get a “550 Spam blah, blah” response, we don't consider that a hard bounce. We analyze not only the code, but the surrounding text. These rules will be customizable too.

Hah! Great! I'm glad you liked your report. Now we need to get you signed up for an annual subscription.

If an email hard-bounces or permanent-fails… it's totally no good? I thought that some ISPs would send back permanent-fail replies sometimes even when that email actually existed. Is that incorrect?

Hi Adam,

There is not an OnSuppressed event yet, however I am sure we will be adding something like that soon. There are events for failures and fbl reports, and that is what feeds the suppression lists though.

In the front end you can view a list of your lists, search lists and remove items from lists.

Yes, something only gets on a suppression list if we receive a response from the ISP indicating that the address is invalid. So there is no threshold because a bad address is a bad address. Soft bounces are not included.

I hope this helps!

BTW, I had a chance to purchase one of your PayScale reports the other day.

payscale.com is really great!
