Hi,
What should the policy be on blocking Google IPs?
No one here can tell you who you are.
This is a very individual choice. Google tries to pump a lot of spam
out, and benefits from having a little legit mail mixed in that many
people want. If there's substantial legit mail from them that you
actually want, you can always exempt individual addresses or domains by
adding them to the local welcomelist.
* 2.3 RCVD_IN_PSBL RBL: Received via a relay in PSBL
* [209.85.208.194 listed in psbl.surriel.com]
* 2.2 RCVD_IN_SENDERSCORE_30_49 RBL: Senderscore.org score of 30 to
49
* [209.85.208.194 listed in score.senderscore.com]
Those matches are justified by what Google actually emits and the
documented processes for PSBL and Senderscore.
Whether those scores suit you is not a question I can answer. In never
see any mail offered by a PSBL-listed IP, so I have no opinion on the
best score for it. That approach may not suit your needs.
You didn't say whether the message this is from was ham or spam...
* 0.0 RCVD_IN_MSPIKE_H2 RBL: Average reputation (+2)
* [209.85.208.194 listed in wl.mailspike.net]
I'm not sure that's justified, but since MailSpike's +2 level is full of
mixed big sources I guess it's at least consistent. The meaningless
score reflects that. If you think you want to protect mail from sloppy
behemoths no matter what, you could give that a strong negative score.
These are IPs used by millions(?) of users that apparently have been
abused
by enough to warrant the above to penalize them, but the alternative
is
either having to welcomelist the sender or somehow remove the IP
locally
from being checked. Both options are only after they've been blocked
at
least once. And this is only one Google IP - how many others could
there be?
Ideas greatly appreciated.
I think it is very easy to over-worry about this sort of issue. PSBL
listings are always temporary and just one IP. If that was ham that got
scored as spam, maybe you should find other ways to protect it. Or maybe
it will clear up tomorrow and not affect any mail that you notice for
weeks. Or years.
