I can never understand why people read email in a browser, rather than 'modern' it seems totally antiquated to me.Whatever happened to the idea of separating data presentation and data display?
I expect a mail server to be able to supply the mail data, and then I may run whichever mail client I wish to display it to me in whatever way I can persuade it to do, in a way that best suits my needs/wishes.
Similarly, why do people assume that mail is sent from an application by a user typing at a keyboard?
I have a few dozen mails sent to me every day by the background process that check the health of my systems and backups (and this is just for my systems at home - when I worked I had far more doing similar things there too). How would I get that to work with OAuth (or similar)?
