This morning I received a spam email where the spammer accidentally CCed everyone, instead of BCCing them. They also seemed to have spammed many people named Donncha, so hopefully none of them reply-all asking to unsubscribe.
It’s not the first time, but they included an “email address” that isn’t an email address. They used my @donncha@mastodon.ie
Mastodon account. They also included my Gmail address, which is how I received the email.

I started receiving email to this blog’s @donncha@odd.blog
address and to photoblog’s @donncha@inphotos.org
address too, but I’ve blocked them already.

If you publish the address of your self-hosted Mastodon account, you might want to make sure you don’t have an email address there too, or you’ll start to get unwelcome emails.
BTW – you should pay for your email, especially if you have self-hosted domains. Fastmail is great. Here’s the post I wrote about Fastmail when I switched over last year.
