I have seend this issue posted a couple times in the past, and wanted to see if anyone could provide their thoughts on what I'm experiencing. Our sending IP was verified as unlisted as late as June 21 at 7AM PST, but an email we sent the next day June 22 at 930AM PST returned several bounces with a range of errors. What I find interesting is that we received all bounces/errors on the same day, but the errors are so different and come from several unrelated recipient domains. All are referencing a SpamCop block. 550-"JunkMail rejected - XXX.mktomail.com [XXXXXX]:55650 is in an 550-RBL on rbl.websitewelcome.com, see Blocked - see 550 http://www.spamcop.net/w3m?action=checkblock&ip=XXXXXX" 550-"JunkMail rejected - sjsmtp.mktomail.com [XXXXXXX]:36064 is in an 550 RBL: Blocked - see https://www.spamcop.net/bl.shtml?XXXXXX" 550 spamcop.mimecast.org Blocked - see https://www.spamcop.net/bl.shtml?XXXXXX. - https://community.mimecast.com/docs/DOC-1369#550 [469OF93uOEyQiJ_Jghl1jw.us376] But we are not listed: Could there be a single root issue, or is it really the case that the error is rooted in each recipient's settings --- meaning we would need to contact each recipient who returned an error and address their settings individually? Thanks!

I reported spammy messages by using the forward method. I forwarded my spammy emails to this email address: submit.XxXxXxXxXxXxXxXx@spam.spamcop.net And here are the results: I got nothing but error messages sent back to me. My question: If spamcop.net gives me nothing but error messages when I report spammy emails, what else can I do then? What are my options and are there any viable alternatives? How do others fight against spammers successfully? [SpamCop] Errors encountered SpamCop AutoResponder <spamcop@devnull.spamcop.net> SpamCop encountered errors while saving spam for processing:

Forgive me if this has been addressed, I searched for "Reported in Error" and "Reported by Mistake" and didn't turn anything up. I just reported something as spam, when in fact it's not. I knew this could likely happen one day, and today was the day. It was this report. How do I cancel, or retract that report, or at least let SpamCop know it was reported erroneously? I'll have to be more carefuly in the future, when perusing the content of the report I just overlooked it this evening.

I've been submitting spam to SPAMCOP for MANY years. Recently I've begun to get MANY results which state: ------------------------------------ No unique hostname found for source: xxx.xxx.xxx.xxx warning:Possible forgery. Supposed receiving system not associated with any of your mailhosts Will not trust this Received line. error:No IP found or Hostname verified: trinity.trinityinternetservices.com warning:Possible forgery. Supposed receiving system not associated with any of your mailhosts Will not trust this Received line. error:No IP found1 ------------------------------------- Whan I look at the message source, it contains the usual "received from", DKIM signature, received by ..., Subject, From, To, X-spam, SpamCop analysis, and HTML message. I can't remember seeing this message in the past - why is it happening now? Lyle
