It depends a lot on whether you need the account for reading email, sending email to your own accounts, or sending email to other people. The first two are very easy to self-host.

But agreed that mass-mailing (even account registration style emails) seems a lot less reliable because of those spam filters.

it's only "difficult" because google, microsoft, etc have conivenced the community that self-hosting e-mail is not possible and for some reason, further propetuated by IT influencers that have drank that koolaid.

all complete bullshit; they arbitrraly occasionally block to protect their moat raping privacy. e-mail is the most rewarding self-hosting capability. like anything, there is a learning curve but at the end of the day: it's easy, stable, a pleasure to host. there are solutions that ease the learning curve. after a while, all the e-mail do make it through.

i'm so happy that my communications are not indexed by these hyperscalers.

stop listening to these pussies claiming how difficult it is. they're projecting their limitations.
