Its a sucky world sometimes. Perhaps Paul complained to ATT/<other-unnamed-provider> with logs and such? :)oh yes. i tried *several* ways to get their attention. however, this kind of activity is so common these days that a noc literally has no choice but to focus their efforts on less common and more damaging things than relayprobing. so i was not shocked that they did not answer me.
So, for <unnamed-provider-X> you have a Abuse Ticket number? Perhaps you could send the one you think might apply to me off-list? :)
so if you're going to block tcp/25 SYNs on outbound, please make sure you block SYN/ACK's on input too, or else you just give the spammers a little more work to do instead of a lot more work to do.Yup, this is in the works also... and yes, someone realized quickly enough that the one-way filtering was dumb. oh well. live and learn!that's good news, thanks for sharing it. any schedule for a fix :-) ??
I do not know what the timeframe is :( Sorry.
