[mailop] AT&T Blocklist

What's going on with AT&T? They're blocking our mail servers left and right (IPs aren't on any other blacklist mind you) and not hearing a peep from abuse_...@abuse-att.net. What's the point of having your blocked message state to send an email to abuse_...@abuse-att.net if nobody is going to mon

Hey Benny, Just an FYI, the list admin's prefer NOT to have the list used for reporting spam.. It's okay to report generic trends, or misconfigurations, or visibility into something new.. (And of course, you are welcome to provide evidence of that.. ) but the list can quickly get consumed if

Re: [mailop] Another 'Verified Email' service on AWS EC2

FWIW, we use Fail2Ban to block all AWS EC2 IPs that have an "ec2-xxx.compute...amazonaws.com" PTR record, and another Fail2Ban rule to block hosts that HELO with "127.0.0.1". We ourselves host on AWS successfully (for more than six years now) and have filed a number of complaints with their sec

Re: [mailop] salesforce phishing emails
