I'm curious to know if there is an easy way to mock an IMAP server (a la the imaplib module) in Python, without doing a lot of work.
Is there a pre-existing solution? Ideally I could connect to the existing IMAP server, do a dump, and have the mock server run off the real mailbox/email structure.
Some background into the laziness: I have a nasty feeling that this small script I'm writing will grow over time and would like to create a proper testing environment, but given that it might not grow over time, I don't want to do much work to get the mock server running.
I found it quite easy to write an IMAP server in twisted last time I tried.  It comes with support for writing IMAP servers and you have a huge amount of flexibility.
How do I mock an IMAP server in Python, despite extreme laziness?
