ANNOUNCEMENT: The NEW invaluement "Service Provider DNSBLs" - 1st one for
Sendgrid-spams!
...a collection of a new TYPE of DNSBL, with the FIRST of these having a focus
on Sendgrid-sent spams. AND - there is a FREE version of this - that can be
used NOW! (well... might need a SpamAssassin rule or two! Your help
appreciated!):
INFO AND INSTRUCTIONS HERE:

This provides a way to surgically block Sendgrid's WORST spammers, yet without the
massive collateral damage that would happen if blocking Sendgrid domains and IP
addresses. But we're NOT stopping at the phishes and viruses - and we're not finished!
There will be some well-deserved economic pain, that puts the recipients' best interests
at heart. Therefore, flagrant "cold email" spamming to recipients who don't
even know the sender - is also being targeted - first with the absolute worst - and then
progressing to other offenders as we make adjustments in the coming weeks.
I fail to see the point: that we do the work that sendgrid should be doing, but
on a duplicative scale?
Why don’t they police themselves?
We’re effectively calling out spam that’s escaped after the fact. What’s the
point of that?
They should be scanning email as it leaves their infrastructure and using rules
and Bayesian filters to know if something is amiss and they need to have human
intervention.
Nothing is stopping them from doing the right thing.
Why should we enable their bad behavior?
The point is to prevent Phish, Spearphish and other bad stuff, not just
"spam"
seems you're sort of late to the party...
Get on board @ Mailop, SDLU, etc lists
