You don't need 24/7 server for receiving email. You can have it offline for a day or two a week and you'd only lose maybe some spam.
I'd call that involuntary graylisting. :D
Many services use email-based login links or other second-factor codes. Email being offline means you can’t log in to or use these services.
Banks also seem to love scolding you when they have the slightest problem delivering you email. (Or also when they see that you haven't loaded their tracking pixels in a while.)
No critical services I use do that. Well, no services I use do that.
But certainly something to be included in personal risk analysis when self-hosting.
