The new buzz word, "cloud computing". Seeing google's email service (supposedly "cloud computing") had 3 serious outages in the month of August alone I really see this as a major improvement... not.I just love the highly informative error message from Gmail's IMAP serverwhen it is down: "System Error (Failure)".
I think it's actually good that the user doesn't get too much of information when the server fails. User can't do anything about it anyway. And too much information could give an attacker more information on how to attack the system better. This error message could be better though (Dovecot always uses "Internal error occurred. Refer to server log for more information. [timestamp]").
BTW. The same error seems to be happening when trying to access a message that was expunged in another session:
x store * +flags \seen x NO Unable to store flags (Failure) x fetch * flags * BYE System Error x NO System Error (Failure) <<disconnect>>
It's been a year, and Google stilldoesn't have an IMAP server that fully implements the function set of thebase specification, much less implements it correctly.
http://imapwiki.org/ImapTest/ServerStatus - GMail is at the bottom of the list. Perhaps some day I should look into it why. I'd guess there are a lot of things they could easily fix.
