the ip that was blacklisted was 194.90.153.34
my error yesterday was that i added "notify sender" in the pineapp system.
i've set everything back so it cannot happen again.
OK I'm guessing that the 'notify sender' setting caused a flood of 'non-deliverable' messages to the forged 'From' fields of spam your server received. You have now corrected this and are now using 5xx during the SMTP conversation instead. Your system no longer sends out ANY non-deliverables, over-quotas or vacation messages?
If ALL the above is true then I suggest a grovelling email to deputies[at]spamcop.net and they MAY de-list you early, providing that the spew really has stopped.
Actually I've just checked and you're not currently listed so maybe a deputy already read this!
Edit: there are no human reports for this IP' which indicates spamtrap hits, which in turn supports my earlier suppositions.
Shalom.
