How to use unencrypted imap connection? (was: How to use non-standard imap port?)

[Nikolaus Rath <Nikolaus@rath.org>]

Hello,

It turns out I mis-diagnosed the problem. It's not setting
nnimap-server-port to "8421" that's causing the problem, but the setting
of nnimap-stream to plain. Using tls or network works just fine, but
encrypts the connection (and I want to look at it in Wireshark).

Anyone have a suggestion how to find out where exactly this setting is
causing problems?

Thanks,
-Nikolaus
