Hi Brian,
I am trying to reach you off-list but the message keeps bouncing at your bkantor.net o365 mailbox due to security settings. I have a question about re-routing my BGP subnet.
Would it be possible to contact me off-list please?
Thanks!

bkantor.net isn't an O365 mailbox, so I don't know why it's bouncing the way you say it is.
Try brian@ucsd.edu and see if that works. - Brian

Oh, I see.
The mail you are trying to deliver to me has a "Disposition Notification To" header line in it. This is a common trick used by spammers to prospect for valid mailboxes, because its purpose is to send the message sender an acknowledgement as soon as the message is opened by the recipient, whether the recipient wants to tell you that they've looked at your message or not.
I don't allow mail wanting those acknowledgement messages because I believe they are a privacy violation, so yours is getting rejected.
Delete that line from your email header and you'll get through just fine. - Brian

Yeah, I have the "read notification" on. Standard thing that I set on my mails to customers to know that they've read my mail. Disabled it and sent another mail, doesn't seem that one gets rejected for now :) Thanks!

Yes, that's it. I feel that is, frankly, none of the sender's business whether I have read his message or not, nor when, so I don't permit those headers to be accepted, and reject the email with an appropriate error message. - Brian

Just curious, but don't e-mail clients ask you whether you want to send the acknowledgement or not? I know Thunderbird asks.

Email clients ask if you want to send a return receipt if they are requested by the sender yes. But I can understand Brian's position. There is also such a thing as a delivery receipt, which is not at the discretion of the email client or recipient, the email server will send a mail returning that the message was delivered, no matter what your other client-side settings are.

Luckily, 'Return-Receipt-To' headers are largely deprecated, and few mail agents respond to them anymore. - Brian

Some do, like Thunderbird. Some don't, I'm told. The particular client I usually use, 'mutt', doesn't respond to them at all. (Yes, it's a crusade. One of the very few principles of mine that the modern internet hasn't destroyed yet.) - Brian
