Hope someone can help with this. Have not been able to find the right search parameters in my searching of the archives.
We want to change our customers from one modempool number to another. To achieve this, we want to send them to a captive server if they use the old modem number, from which they can only escape by changing the modem number they ring - or rather having our little program on the captive server do it for them.
For webmail customers this is already fixed. It is our pop and imap customers with which I have a problem. My question is how do I configure a uw-imap server to direct all attempted logins, whether by pop or imap, to the same mailbox which delivers one message to the person, a message which he/she cannot erase in the mailbox (so that others can receive it). If the accepted solution requires one mailbox for pop and one for imap, that's okay.
If there is an easier solution using something other than uw-imap, feel free to suggest it.
You should consider that this is likely to irritate many IMAP users. IMAP clients often cache the content of mailboxes. If the view of the users' account suddenly removes all their messages (both in the inbox and all folders) these clients are going to slavishly toss all of the cached email. That will then mean a lengthy resync once they change their settings and dial back in. It wouldn't impact POP users since an empty inbox (save for you single notice message) does not remove or invalidate email a user already has locally.
At the very least, this approach should be arranged to be a final catch-all method of notifying users. Then, only IMAP users who ignore the earlier notices would be impacted. I would consider this as an initial or primary means by which I learn of the dial-in changes to be highly annoying and heavy-handed due to the side effects. A brief, administrative email sent a few weeks before throwing the switch would suffice, at least for me.
