When reporting a spam that got through to SpamCop, I noticed the following in the report: listed in ( ) is an open proxy


Here is the log entry for the spam in question (it seems to be the case on about 1/2 the spam that gets through, so this is only a representative case):

23:45:33 3 SMTP-370(NOON-BL31RUG96I) Failed to verify. Real address is []
23:45:41 2 SMTP-370([]) {S.0001662901} received, 1169 bytes

They were apparently added to the DNSBLs after you received the spam. The addition was probably as a result of this spam.


IP Address was found in the CBL.

I get this, too. Unfortunately, some of us get hit before the addresses are added to the DNSBLs we use. That's one of the reasons I use spamtraps as well.
