Virtual Users And Domains With Postfix, Courier, MySQL And SquirrelMail (Ubuntu 10.04

[Doles]

Hi there.
I have run through this Howto, and at the end result I get the following error from squirrelmail.

Error connecting to IMAP server: tls://localhost.
0 :

It is happening before any authentication is done because I've put bogus details in and get the same result.

I've done everything according to the HowTo, and sent the Welcome email with mailx. This didn't work :/ I tried to send an email to my gmail from mailx but no luck. Could that be a clue?

Squirrelmail configtest shows this at the end

Checking outgoing mail service....
    SMTP server OK (220 server1.example.com ESMTP Postfix (Ubuntu))
Checking IMAP service....

    ERROR: Error connecting to IMAP server "localhost:143".Server error: (0)

So there is definitely something wrong with courier-imap

Any ideas?

I've tried dovecot as a replacement, but got a different error, still IMAP related but error:111. I'm unsure how to set up dovecot to replace courier like this

Thanks for any help

i don't see anything on port 143?

Yes, you're right. What about the ones that say

localhost:imaps

and

[::]:imap2

Are one of those 143?

[Mark_NL]

imap2 = 143 .. but it's on ipv6

Ahh I see now. But where do I change it? I remember seeing it, but I can't find it now.

Thanks mate

[Mark_NL]

run: /etc/init.d/courier-imap start

netstat -tapn | grep :143

[Doles]

tcp6       0      0 :::143                  :::*                    LISTEN      19371/couriertcpd

Still on ivp6. I'm not quite sure why that would cause it to not work. And how do I fix this?

[Doles]

doles@server1:~$ sudo telnet localhost 143

does this give any clues?

[Mark_NL]

well it runs .. and ofc, i forgot ::1 .. if it's ipv4 it'll forward it to ipv6 so that's no problem.

Let's put it this way: If you followed the how-to here on how-to-forge by the letter, everything WILL work .. so i'm thinking you forgot a step, made a typo or made custom changes to the installation.

So i suggest you run through the how to one more time

[Doles]

Ah yes, thanks mark, I ran through the howto again and now have it working. I'm not sure what the typo was, but It was a typo or a misunderstanding.
Anyway, all good now.
I can pass local mail from users on the mail server, but can't send or receive to gmail, and I can send to my ISP mail, but not receive from it. Anyway, I think it has something to do with MX records or something for me to figure out myself.
Thanks for your help
