Suspicious/odd "Mail delivery failed: returning message

[davidq]

I've now received three of these messages, each from a different one of my Spamgourmet (SG) addresses. In each case the message was identical, save for the SG address. Each was apparently addressed to support@ups.com. Here's what seems significant from a message: (With ... in place of my SG ID.)

A message that you sent could not be delivered to one or more of its recipients. This is a permanent error. The following address(es) failed:

support@ups.com
SMTP error from remote mail server after end of data:
host email-vip.ups.com [153.2.242.49]: 554 Transaction Failed. Spam Message, not delivered.

Any thoughts on what's going on?

I seem to have the same issue, and it's costing me money.

When an email from Ameritrade bounces, Ameritrade prints and snail-mails the client instead (claiming that it's legally compulsory for them to do so), and they charge $2 every time it happens.

OTOH, Ameritrade has proven that they cannot be trusted with any non-disposable address, because they leak their addresses to spammers.

As a tempoary tip, I guess you can set up a Gmail account with 2 filters:
1) Forward messages based on X (from address, subject, etc.) into your real address (assuming you trust Gmail better...).
2) Delete everything (does it work on the messages from 1?)
