Important reminder, if you own a domain name and don't use it for sending email.
There is nothing to stop scammers from sending email claiming to be coming from your domain. And the older it gets, the more valuable it is for spoofing. It could eventually damage your domain's reputation and maybe get it blacklisted, unless you take the steps to notify email servers that any email received claiming to come from your domain should be trashed.
Just add these two TXT records to the DNS for your domain:
TXT v=spf1 -all
TXT v=DMARC1; p=reject;
The first says there is not a single SMTP server on earth authorized to send email on behalf of your domain. The second says that any email that says otherwise should be trashed.
If you do use your domain for sending email, be sure to add 3 records:
SPF record to indicate which SMTP server(s) are allowed to send your email.
DKIM records to add a digital signature to emails, allowing the receiving server to verify the sender and ensure message integrity.
DMARC record that tells the receiving email server how to handle email that fails either check.
You cannot stop scammers from sending email claiming to be from your domain, any more than you can prevent people from using your home address as a return address on a mailed letter. But, you can protect both your domain and intended scam victims by adding appropriate DNS records.

I can't decide if I want to go back to Seattle, specifically, or if I just long for a life closer to where things are happening. Where I don't have to walk half a mile just to get out of the houses and neighborhoods.
@mcc The other day I spotted a hoodie with a QR code containing a URL to its own store page.
@mavica_again this is, legitimately, a mouse cursor. it's included with the CD-ROM versions of Moraff's Mahjongg games.
it is the only time i've ever felt like my own mouse is getting in the way of playing the game and it is also the greatest thing ever
@june i've got a friend named maple who does pixel portraits; i've got one set up on this profile right now. https://maple.pet/commissions
@PlayHistory Henk Rogers gnawing on an L-block is definitely something I needed to see today πβ
@vga256 I like that this collection has Koi-Koi in it. that game is fun as hell and more people should learn how to play it.
every once in a while i stumble across a great DS title at a thrift store
todayβs find was Club House Games - a relatively early title that took advantage of the DSβs architecture
one criminally underrated and underused DS feature is βsingle card download playβ - which lets you play against other DS players who *do not* a copy of the card themselves. it wirelessly transmits the game to them for ad hoc competitions.
i love that the first owner of this bought it at a local Zellers. π how i miss your vinyl offgassing shoe aisles and $3 PC bargain bins
He/him. Puzzle-Adventure Hybrid with RPG Elements. Supports 3D Acceleration. He Is Essentially What He Believes. Just in case, π, LGBTQ+ π, DOS π, ππ©π.
