Someone is sending spam about Perfectly crafted Pieces under the identity of one of my many email addresses. Unfortunately, there seem to be a lot of mail servers out there, that do not check SPF records and simply send error messages about unknown mailboxes and the like back to my address. Got at least 40 of those in the last three hours. Many of those even saying that the message was not accepted because it is spam. Doh!
Shameless plug: If this post was useful to you, please consider buying yourself something from one of my Amazon stores: US store, UK store, FR store, DE store, CA store. If you're not into Amazon, why not donate something to GNOME, Mozilla or Wikipedia? Thank you!
I used to have “catch-all” enabled for a quite generic domain, until, a few years ago, some spammer used @domain as his sender…
At least I found out my mail server would handle about 5.000 bounces per hour before collapsing that way…
I was suffering the same yesterday. Unfortunately the mails were completely in russian so I’ve no idea what the spam was about…
