I'v been thinking the same thing. One issue that has crossed my mind is that how POP3 clients work in case like this when user leaves his/hers mail on the server.
Depends on the client. Quite frequently, the pop-client will get confused the next time it connects and gets the real mailbox, and will download everything that was still on the server.
Same thing may happen in the case of IMAP and 'disappearing' namespaces and subscriptions. I would personally not risk it, and instead have dovecot give a customized error message "ERR Sorry, due to an unforseen problem our mailservers are currently inaccessible. For more information, please see http://our-website.us.org/news/?item=115" or such :)
Ah, I see what you mean, didn't think of it like that. In that case a custom error message may be the best move and would work well in a high load situation (stopping new connections). Most pop clients tell you the server error message when one appears so it might work for that too.
