There are more reasons than a conspiracy to get you to pay a subscription...
True, but in most or almost all, it is not your sendmail or your server that has anything to do with it. A bounce would indicate a problem or other things...but 'defer' could mean anything. I get a lot from yahoo, both with the stupid ID things and one server without them. They can defer for a while.
I seldom get a defer from anywhere else, but a mailout of a large list could get some.
But I see nothing you can do at your end if you are sending it other than sending a letter to the deferring agent if you have the email, you know who it is. If it is a big company like yahoo or hotmail, I would just send a letter to the recipient and tell them about the issue so they can expect a delay.
Anyone notice how little junk snail mail they are getting now? Or how many snuggie blanket ads they are receiving via email....strange world out there.
Bulk mail is still expensive, and it is easier for the scammers to send e-mail then to try and get a bulk mail piece past the postal inspectors.
Looking at my stats for the year, At the beginning of 2008 I was rejecting (at MTA) less than half a million messages a month. Now it is over 2 million a month. That is pre-processing rejections on a system with less than a hundred people on it. I can imagine what you ISP level guys are dumping!
