Spamcop blacked by ubl.unsubscore.com


Recommended Posts

It appears spamcop reporting ( is blacklisted by ubl.unsubscore.com. See http://blacklist.lashback.com/

One annoying thing, is the web interface on spamcop.net indicates a bounce back failure but does not give back the bounce back. Takes a little longer to investigate the cause when only a partial line is given back.

Specifically this is what is displayed on spamcop.net:

Bounce error

Your email address, john.lauro[at]covenanteyes.com has returned a bounce:

Subject: Delivery Status Notification (Failure)

Reason: 5.1.0 - Unknown address error 554-'5.7.1 Service unavailable; Client host [=

Any thoughts on ubl.unsubscore.com? Are they a good list to include or too many false positives?

Hmmmm, interesting.....

multirbl.valli.org's checker shows the IP address as listed, with a comment about "Sender has sent to LashBack Unsubscribe Probe accounts"

I'm not quite sure what that means or what the solution is.
