Alot of innocent victims are getting blocked because there respectible large ISP has a spammer on 1 IP out of a few million. This gets the /13 or how ever many they have on the SORBS RBL and causes email blocking for the spammer plus millions of others. For instance I know a guy who uses Comcast and has his ip BL'ed
SpamAssassin can be configured to use or not use specific DNS BLs. You should configure it, or at least have an option to NOT use BLs that check if a SMTP connection comes from a dynamically-allocated IP address from at least the largest ISP's.
Please understand that I have called Comcast (my ISP) and ask them to get my dynamic IP address removed from a list of dynamic addresses, they refused to do so. I am using a dynamic IP address. Dynamic IP addresses are not “bad”. The maintainers of lists of dynamic address lists (e.g. MAPS DUL) would never be convinced to remove an actual dynamic IP from their list just because it inconveniences a user. If they did, their list would become less reliable, and therefore less valuable.
We’re dealing with a configuration issue here – one that spam assassins administrators need to work on. SpamAssassin can be configured to not disqualify messages originating from a dynamically allocated IP address. I’m sure you can find someone within your company who can figure out how.
Thanks in advance for fixing this!
Well, MAPS defaults to score of 0 (never check). Most of the sorbs lists are scored pretty low.
I believe we shouldn't have an issue if:
1) The users on the dynamic IP are sending through their ISP's SMTP relay. 2) Trusted networks is set correctly 3) Trusted networks works properly (open bugs on this, I believe?) 4) SA is aware that the RBL in question is a "dialup" type list.
I believe the way SA is supposed to work in this case is: "ok, someone at 1.2.3.4.dynamic.big.isp sent mail though mx-relay.big.isp. Since they went through a relay, I don't care if 4.3.2.1 is on a dynamic IP RBL".
If you are on a dynamic list, and are not sending through a relay, well, that is a problem...
Correct, a maintainer of a dynamic IP rbl is not going to remove and IP from a list because of your inconvenience... if they did, you'd have to call them every time you changed your IP!
