As of this second I have all 3 clients I mentioned fetching e-mails while they’re open. However none of them fetch e-mails in the background, and geary/evolution seem to just… break sometimes and I have to redo the process to add business gmail/proton accounts to it.
My main issue is the fetching e-mails in the background though, it doesnt feel to me as if it should be something that difficult or niche.
