When they say “do not meet outlook technical standards” they mean it. Go through Every Single Bit of your technical setup and compare it against their requirements. If, at any point you think “oh, no, that won’t matter that I’m doing it a little different than they say…” trust me, you’re wrong.

Re: [mailop] Junk filtering as a tool for unfair competition

One of the things I’ve deduced over the years from discussions (oh so many discussions) is that one of the major factors in SmartScreen filters is how recipients are interacting with the mail. It is a direct measure of how your users are interacting with the mail. This means a few things. 1)

If it’s just a couple recipients at the domain take the hint. More than likely those specific recipients have manually blocked the sender. They’re done with your mail. Stop mailing them. Laura Sent from my iPhone > On Sep 20, 2019, at 5:24 PM, Andy Onofrei via mailop > wrote: > > HI Erwin

Re: [mailop] Resolving issues for several yahoo domains?

There was a point in time where if you didn’t limit the number of messages per session a few of the larger mailbox providers would simply cut you off. The issue was some spammers were making hundreds of connections and then holding them open for days (yes, really, more than 24 hours at a time).

In my experience, when the bounce message says "Please contact your Internet service provider since part of their network is on our block list (S3150).” That means that Microsoft is seeing problems across a wide range of IPs in a space and they don’t have a clear picture of where the customer bo

Captchas aren’t a FUSSUP. They’re meant to address a specific problem - listbombing. COI contributes to the problem of listbombing. SMS challenge is going to make that worse. 1000 SMS messages in an hour is a problem. There are people who’ve been working on this issue for years and I’m sure th
