I keep a single domain for distnct emails. It’s not anonymous in the sense that anyone with half a brain could put 2+2 together and figure out who I am. It’s highly useful for three reasons: If I suddenly get junk mail on a specific email, I tell my server to deposit them in in the bit bucket. Next, the algorithms aren’t necessarily smart so having a different email for every login a) makes it harder to profile me, and b) it’s more secure. Hackers will waste a server month trying to open my lemmy email in all the money stores.

I use my own cloud server for everything except mail. For mail, I will probably move to Tuta. Their apps have issues, but they are open source.

definitely. I run one on my own server. It doesn’t do mail though.

I’m 73 and I understand nothing. Does that help?
