Courier-imap: no telnet

bravecobra · Posted: Thu Dec 26, 2002 9:26 pm Post subject: Courier-imap: no telnet

I've got the following problem:

I have qmail installed and that works perfectly. Now I would like to offer the maildirs as IMAP folders and I want to use courier-imap to do that. Also POP is to be achieved

I've installed the qmail-pop3d and that one works perfectly. However the courier-pop3d does not seem to work for some reason(with the qmail-pop3d disabled of course). I'm using PAM authentication.
When I try to telnet the daemon (# telnet localhost 110) for POP, he connects and then says the foreign host closed the connection, like this

Are you sure that the daemon is running ?

Is there anything in the logs ?

What gets returned when you execute :

/etc/init.d/courier-pop3d status

Yes, daemon is running and there is nothing in the logs to be found. I find it all very strange too.

Just for testing, I diabled the qmail-pop3d and enabled the courier-pop3d daemon, and everything worked ! Are you using the latest version of Courier-Imapd ?

Here is a working copy of my /etc/courier-imap/pop3d with no modifications except that I removed the comments.

I think the problem lies in the authentication daemon. Tried your solution. Don't work!

The only difference between my authdaemon and your authdaemon configuration is in the authdaemonrc file.

The authmodulelist line:

authmodulelist="authcustom authcram authuserdb authmysql authpam"

And my version line:

version=""

Nope, tried that one too, but it didn't work. Something very strange is going on here. I'm guessing something went wrong during emerging.
What should my USE look like?

Do I need an MX record in my DNS server in order to get this working?

No you do not need an mx record in your dns to have this working. I don't think it's a problem in authentication, I have seen many problems with courier-imap and authenticating, all of them had the same symptoms, you can login, and you will randomly get authenticated, or not authenticated at all.

Maybe it has something to do with permissions, or something else. Are you binding to a specific ip?

yep fixed ip 192.168.0.2, I've tried setting adress to 192.168.0.2, but that doesn't help. I guess something happens in the emerging although I don't get any errors, only one warning (can't really remember which one, but I was told it was innocent.).

but when you bind courier-imap to the ip 192.168.0.2, then you should connect to that ip instead of 127.0.0.1, did you try that also?

So, what does the following do:
telnet 192.168.0.2 110

The same thing. Connection closed by foreign host.

I'm in a similar sounding situation. Recently my IMAP (courier-imap-1.6.2) stopped accepting login's

I am having the same problem

PS - Gotta love Stimpy!

Works here, using pam 0.75-r10. Haven't tried r11.

Only difference I saw in my /etc/courier-imap/authdaemonrc was this

stimpy · n00b Joined: 18 Apr 2002 Posts: 49 Location: NZ

I have to admit to a shameful amount of incompetence :oops:

Although I'd restarted imap, rebuilt everything, checked the configuration of authentication options for courier, had authdaemon running, i'd forgotten/overlooked restarting the authdaemon.
It only gets started on my system due to a dependency in courier-imapd, so although I'd restarted courier-imapd, the dependency was being statisfied by its earlier invocation.
Now it works just fine... Sigh!
(now to fix my libgnomeprintui compilation problem!)

All I should need to have running is...

postfix
courier-imapd
courier-imapd-ssl

Am I missing something?

stimpy · n00b Joined: 18 Apr 2002 Posts: 49 Location: NZ

you need your authdaemond running as well I believe. It should start up "Transparently" if you start courier-imapd through a dependency in /etc/init.d/courier-imapd{,-ssl}

(It has to be configured as mentioned above as well obviously.)

It will start a process authdaemond, authdaemond.plain, or whatever is configured.

Isn't the authdaemon, in my case authpam, loaded in /etc/courier-imapd/authdaemonrc with this
