I've had my domain (straightpathsql.com) for a few years now. I host my e-mail with Google Accounts for business and have for awhile. ALl of the sudden in the past week I am starting to get a lot of postmaster delivery fail notices from various domains, most of them involving bogus e-mail addresses at my domain (
[email protected], for example)... My assumption here is that someone is trying to relay on some other host (not my hosts which are secure through google apps for business, I presume) and there isn't much I can do to stop it. But I just want to make sure there isn't something else I need to be looking at here.. An example delivery fail notice is below.. I know nothing of those addresses below and they look like garbage...
(Quick edit: the reason I get these messages is I set myself up as a catch all, so it doesn't matter what e-mail you send a
note to at my domain, I'll get it if the account isn't setup... All of the failure messages are sent to bogus addresses on my domain)
The following message to <
[email protected]> was undeliverable.
The reason for the problem:
5.1.0 - Unknown address error 553-'sorry, this recipient is in my badrecipientto list (#5.7.1)'
Final-Recipient: rfc822;
