Undelivered Mail Returned to Sender - SPAM


Presumably I’m not the only one getting hundreds of unfiltered mails like this every day?

Please filter it DREAMHOST!!!



FFS am I the only one getting this disguised Viagra spam?

Up to a 100 mails a day now!


So you say you are getting returned to senders? But you think it’s spam to your email account.

Have you studied the full headers? The reason I ask is perhaps one of your domains has been compromised and is being used to SPAM others and the “returned mail” are valid bounces.


OK thanks for the bad news :frowning:

I’ll check the headers…



Another possibility is that you’re the victim of a “backscatter”: a spammer is sending out emails with your email address in the “From” field, and a bunch of the bounces are being (incorrectly) sent to you.


Thanks Andrew,

Coming in thick and fast today.

Presumably there is nothing I can do about Backscatter now that it’s out there?



Not really, I’m afraid. There’s no good systematic way to distinguish bounce messages regarding spam from “real” bounce messages — or, indeed, from normal mail.


OK thanks, I mailed DH support and sent a header off. The mails seemed to have stopped for the time being, so we’ll see…


How to filter this with Dreamhost ?

Spamassassin does not stop this email.

It seems that one of my website has sent a message to an Email address that is not available anymore, then I get hundreds of “Undelivered Mail Returned to Sender” messages.

What to do ?
