I have had quite a few of these lately , this is the result of spam tosser spoofing email from my domain, but the bit that has pissed me off here is the fact the target email server even bothered to send a reply. I know the email is spoofed as it has breached the SPF, so why even bother responding, Just delete it. respond during the SMTP conversation, not afterwards Apparently almost 90% of all email on the internet is spam, but how much of that is bounces and “no user here” errors from mail servers with admins who have a 12th centry idea of server config
I had a lovley surprise this morning, 1600 bounced spam emails in my “selective catch all” mail box
I use the term selective, as it has a huge (3000+) blacklist, that and the RDNS connection filtering I run, keeps my normal spam, in the mail box, down to less than 10 a day, with some 3000 being actively rejected.
There is a big debate around whether “catch all” is a good idea these days, But I find it soooo usefull, to be able to use a slighly different email address for any site I register with, especially when outfits like autotrader (autotrader@) leak email data to nigeria like a holey thing and inteflora (flowers@) sold my email address on,
This mornings little treat was not rejected by the RDNS process as they all came from legit mail relays, as bounced email. Which basicaly mean some arsehole is spoofing email from my domain. having been hear before, it is usually followed by a barage of don’t email stuff like this please email from the less astute netizens
I also have reason to believe that one of my work email address’s is being use to spoof spam too, as I have one or two bouced email arrive there too
