Can nginx be used as a proxy for IMAP, so that multiple users can
connect to nginx but the proxied server only sees one connection? If so,
how would this be configured?
Background: We have 20 users who all need access to read/move emails in
a single IMAP mailbox, however our current hosting company is limiting
our connections to one “user” per IP, or around 10 connections (since
most mail clients open multiple connections to the server).
