Sure, I am married. But if I tell my wife, WHY IMAP is better suited for this case, and she refuses to use it, she has to live with the disadvantages.
I know, that IMAP has other disadvantages (for example slower), but just to use webmail from anywhere in the world, and to use SpamAssassin, I would never switch to POP3 again.
I would just switch her mailclient to IMAP, she probably will never notice the difference

BTW: Greetings from my wife Beatrice.
