Someone decided that brvty – dot – org would be a nice domain to use as a return address for their latest spam campaign. I don’t know how many emails they sent out but I got back over 3700 bounces in a couple hours time. Close to 40 megs worth. I don’t actually have or use any brvty email accounts, so I just set the server to delete anything that comes in on that domain. Works for now.
Is there any way to combat this type of crap???
If your host is running procmail you can put a simple rule into your .procmailrc file to handle this:
# Delete any bounce messages that are not addressed to me:
:0
* ^FROM_MAILER
* ! ^To:.myname@mydomain.com
/dev/null
That’s essentially what I did. It all goes via the bit-101 domain, which has a few valid addresses. But any unrouted mail gets discarded.
Did you consider removing the MX record for the domain… especially since you don’any email accounts configured?
Another recommendation would be to set up a SPF record in your DSN so that receiving mail servers can easily identify incoming email as fraudulent and delete it without having to process it. Set your SPF record to be listed as “v=spf1 -all” More info is available at:
