Nextcloud, Qbittorrent, Truenas and loads of other svcs take optional email credentials for sending alerts and other features (eg. password recovery for nextcloud).
What email providers do people usually use to make this process simple to set up? For example, Microsoft doesn’t allow basic auth anymore so it’s supposedly not possible to use via most of these setups, and some other services seem like they have a low inbox size (does this matter?)
I already listed a handful of other platforms that check all those same things without being a pain in the ass to host, being sucky to use, or requiring approval from your ISP.
Uglier than email? Nah.
Yes, NTFY is another example I already gave.
No it’s not.
It shouldn’t be used for accounts. That was my entire point. I host a dozen services and half of them no one else can use because the software mandates email verification, which I can’t use because my ISP doesn’t think I should be allowed to for some reason.
