dummy IMAP server for when server has moved

I'm moving the mailserver (imap).

In the last century, when everybody was using pop3, I made a script which allowed everybody to login, and fetch a message saying "Hey, update your settings".

Now, everybody are using imap, which seems a little more complicated... Is there a simple dummy imapd server available which does that?

Or just a script (netcat?) which can collect the usernames, so I can contact the few remaining users?

Solution

  • In theory the simplest of scripts will do:

    #!/bin/sh
echo '* OK [ALERT] Mail has moved, ask Leif'
echo '* BYE'

    In practice the ALERT may or may not be displayed to the users.

    Capturing login names is more complicated and perhaps not worth the trouble.
