I thought I'd post this here first, before I check the kbase (exercise in futility that it is): Every so often my Mac.com account in Mail comes up with error messages saying "Authentication failed". I re-enter my password, correctly mind you, and still, no dice. I try quitting the app and then relaunching, no dice. Sometimes if I look at it cross-eyed, mumble Druish incantations under my breath and unchek the "Use authentication when sending mail" option, under SMTP, and then take my account back online it comes back up...sometimes it doesn't. I've never been able to find a concrete action that fixes it. It's completely random. This is happening on two separate machines, so I know it's not a corrupted prefs problem (I tried trashing it anyway, no dice). Is the new webmail service screwing me up? It seems like I've only really begun seeing these symptoms last Friday, when the new BETA service started. Any thoughts?
