I ended up giving up on that after one too many websites rejecting my custom domain (which I’m the only one using) on signup. These lazy / ignorant colleagues are annoying -_-‘

I've been using a similar scheme for about 7 years now and have never had my email rejected by a website on signup.

The American Kennel Club rejected mine because the domain was “too similar” to their name. I guess just because it had a “kc” in it? Completely bewildering.

I use this scheme ([email protected]) and one that I remember blocking for this reason is Aliexpress/Alibaba - [email protected] was rejected so I use [email protected].

No idea what sort of security this is supposed to provide.

It happens rarely, but some only accept a very limited number of domains (ie Gmail, Outlook, etc).

They probably see it as some sort of security / anti-spam mechanism.

I use a .xyz domain for my personal email, and I sort of regret it.

My emails have a tendency to become spam filter bycatch, to the point that when I was job hunting last year I'd have to ring people after I sent them my resumes etc. to confirm they actually received my email.

And when I give people my email address, I usually have to assure them that [email protected] is a legitimate email address and not a joke (it's not actually steve, but you get the point).

I host my own email server, and .xyz is one of the 2 or 3 TLDs I went in the config files and manually blocked since nothing but spam comes from it (and lots of it).

Definitely would not recommend using it for your personal address.
