Hundreds on undeliverable emails.

Since 23:44 last night I've had 140 "undeliverable/blocked" email notifications from loads of unknown mail servers.

I've no idea where they have come from or who sent them.

What's going on?

Just someone using your domain name for spoofing spam. If you look at the sender, you will see random names @ your domain.

These returns usually go away after a few days. It is a pain, but not usually a problem.

Only 140. Lucky you. I hope they stop soon as there is nothing you can do about them.

Spammers tend to send out in large quantities. This is just a part of owning a domain name I'm afraid! You've already done what you can re: SPF records.

You could always temporarily set default address for unrouted email to discard for a while. As the spam emails will all be to "strange" recipients @ yourdomain this will stop them getting through to your mailbox.
