When did SpamCop start being "quite good"?
Granted, I think the last time they blacklisted one of my mailing list
servers was a few months ago (as near as I can tell, spammers were
targetting the mailing list subscription addresses, and SpamCop
apparently decided that receiving subscription challenge messages was
unacceptable... not that they ever notified me or anything, despite
their stated policy to the contrary). The last I heard, the SpamCop
admins were of the erroneous belief that ALL bounces could be avoided
by simply verifying that a message was addressed to a valid recipient
during the SMTP conversation, and therefore considered *any* blowback
to be an offense worthy of blacklisting.
If they've changed their policy, I'm glad to hear it, but this is news
to me. They haven't even updated their webpage.
http://forum.spamcop.net/scwik/MisdirectedBounce still says that
"unsolicited bounces" will get you blacklisted. They still recommend
several qmail patches to "fix" the "problem" of unsolicited bounces
(http://spamcop.net/fom-serve/cache/329.html#bounces), though of
course this problem cannot be "fixed" without radically changing the
way email works.
Personally, I can't recommend SpamCop until they demonstrate a better
understanding of the complexity of the problem they face.
But to each their own, I suppose.
