IMAP help ("no registered handler")

This has been driving me nuts.

I'm currently using GNU mailutils (and at this point, it seems most people recommend using either UW-IMAP or Courier-IMAP) to get access to POP3 and IMAP4. My MTA is sendmail.

I'm attempting to filter my mail via procmail but I can't seem to connect to the IMAP server. Here's what I get when I telnet:

Code:

sohmc@bart:~$ telnet localhost 143
Trying 127.0.0.1...
Connected to localhost.localdomain (127.0.0.1).
Escape character is '^]'.
* OK IMAP4rev1
1 login sohmc abc123
1 OK LOGIN Completed
2 namespace
* NAMESPACE (("" "/")) NIL NIL
2 OK NAMESPACE Completed
3 select ~/mail
3 NO SELECT Couldn't open /home/sohmc/mail, No registered handler

Is this specific to GNU mailutils or should I expect similar results with Courier-IMAP?

I'm fairly new to the whole maildirs idea. (Yeah, I'm still using the mbox format.)

I would not recommend uw-imapd, it only supports mbox format mailboxes and they suck horribly. Courier will do Maildir which will perform a lot better and has a much lower chance of losing mail should something go wrong.

Thanks for the suggestion Noth.

I've actually decided to go with dovecot. It came with fedora, and it's working...for the most part.

I have fetchmail to fetch my mail, and fetchmail calls procmail. It might be different if you have your own mail server listening to incoming mail. Procmail filters the mail and puts it in the MailDir. I don't think procmail has to connect to your IMAP server, it simply dumps all filtered mail in the appropriate maildir. I recommend using maildirs, not monolithic mail boxes. Check the procmail man page how to deal with that, it has to do something with a slash behind the directory name or so.

I use Dovecot too, no problems during the past 6 months. KMail is my IMAP client on 3 different boxes at the same time.
