The reason for wanting to interact via IMAP is that I want to use the 
script to report emails which have been manually verified as spam... so 
any strategy at mail delivery time is not going to meet my 
requirements.  I wanted to use Ruby and Net::IMAP for two reasons... (1) 
I've been looking for an excuse to write something in Ruby... and (2) 
Ruby's standard library Net::IMAP supports add_response_handler() - 
which looks as if it will allow me to neatly implement a process driven 
by other IMAP clients moving messages into a "special" IMAP folder 
without any need to do polling.  I'm in the early stages of 
investigation...

I'm not sure why you want ifconfig - anyway - here it is:

Here's my /etc/dovecot.conf (comment lines removed for brevity)

I doubt that it is due to not-listening as I get a "NO" response back 
over IMAP (accoring to the Ruby Docs) - so I must have established a TCP 
connection to the dovecot IMAP server.  I'll have a play with 
auth_verbose and the logging functions...

All my imap messages seem to go into /var/log/messages (on Gentoo Linux) 
- but the only failure messages I get are like this:

Sep 14 16:33:31 gifu imap-login: Login: sjh [127.0.0.1]
Sep 14 16:46:09 gifu imap-login: Disconnected: Inactivity [127.0.0.1]

Will do - any specific explanaitons as to what's wrong for me are still 
welcome :-)
