Hi,

i had the problem with the BlackLists (RHSBL) as written here.
Now I disabled the BlackLists (RHSBL) and installed the new update.
But, how did I get the mails that where bounced?

You will not, unfortunately. As they were bounced, other parties mail server will not resend as they received a permanent failure message.

Would the senders not have received bounce messages??

Or depending on the bounce id the mail could be re-tried for any time up to 7 days before issuing a permanent failure notice.

NO THE MESSAGE WASN'T A RETRY

The error is 550 UNDELIVERABLE.

So as we use the BlackLists to try to Avoid SPAM, can we setup the postfix in a way that If the blacklist is down it still accepts the message ? Or do we have to avoid the blacklists at all ?

I don't think anyone can afford having their messages discarded by a dummy server that drops if it can't check do a RBL check.

Does anyone knows how can it be done or Should we all go ahead and remove the RBL Check as it is not stable ?

If a RBL/SBL list server is down, it will not cause what happened.  The list server in question was not "down", it was up and purposely sending out:

550 This list is offline. Please stop querying for it.

If someone configures one of their RBL/SBL list servers to do that (fairly crappy thing to do IMO), then there is nothing anyone can do about it.  It would have been much "nicer" to send out something different like a 450 reply but they decided on the 550.

Does anyone knows how can it be done or Should we all go ahead and remove the RBL Check as it is not stable ?

There is nothing anyone could have done in this instance.  If you are concerned that another RBL/SBL list maintainer will do a similar unconscionable deed again, then I suggest you disable your RBL and SBL lists, that is entirely up to you.

BTW: The dev team discovered the problem at 9:00 am, diagnosed and found a workaround by 12:30, posted the issue in the forums and updated the wiki by 1:00 and released a patch by around 3:00.

P.S. SME doesn't use postfix.

Yes they do received a bounce message, but on the sme server side there is nothing an admin can do...if the sender is kind enough he is going to resend the mail...or try an alternative email direction...or try a phone call...but in the end the mail was bounced...

That is exactly how the dev team figured it out, one of them received a bounce message and started investigating.

Yea, well...i figured it out at the next morning because my mailbox was completelly empty, its strange to not have at least 3-4 spams at the morning...so for once KUDOS SPAMERS!! LOL
