Coincidentally, this is the subject of the talk I "gave" at Emacsconf
last week! All server variables defined with defvoo (so all the nnimap-*
symbols in your server config) are global variables, but the
server-specific values are copied into the global variables while that
server is the "current server". So you'll only see the relevant value --
the value Gnus is actually using -- if you edebug a live connection to
the server. I hope that makes sense, apparently I still have trouble
articulating how this works.

I would close the connection to this imap server, edebug
`nnimap-open-connection-1', re-open the server, and check out what's
going on. You'll be guaranteed to see the server variables as Gnus sees
them. Given your config above, I would expect nnimap-stream to be set to
'network, but I don't see how Gnus would be setting nnimap-address back
to "localhost" since you gave it a value.

I'm also confused.
