SpmCop is forging its own mail...


Recommended Posts

"A Forum for those things that just plain go wrong or don't work as advertised."

Seems to cover it.

This weekend SpamCop's emailed acknowledgements of our reports started to come from a new IP,

Mail server log extract:

Feb 25 22:59:51 mail6 xm[8046]: 31PMxYmR020727: [], SPF RECORD [v=spf1 ip4: ip4: ip4: -all]
Feb 25 22:59:51 mail6 xm[8046]: 31PMxYmR020727: [], [AS16417], spf [mfrom] test results for [spamid.0@bounces.spamcop.net]
Feb 25 22:59:51 mail6 xm[8046]: 31PMxYmR020727: [], [AS16417], spf [mfrom] result fail (Mechanism '-all' matched)

SPF FAIL, not to mention no PTR record

$ dig +short -x

and the IP being on eight of the blocklists that I use.

Our system auto-reported 19 of these to SpamCop before I managed to stop it... :(
