pop3 service alone is failed in "The Perfect Setup - Debian Sarge (3.1)"

[nandhu]

Hi Falko,

This time I tried Debian Sarge 3.1 instructions on my Kanotix RC-11 version.

Everything went fine not even a single error. Also I omitted Courier section.

After installing ISPConfig and logged in as admin. I selected the Services section and found the following:-

Web-Server: Online
FTP-Server: Online
SMTP-Server: Online
POP3-Server: Offline
BIND-Server: Online
mySQL-Server: Online

and my nmap on localhost shows the following, i could not see any 110 port in it. Could you please tell me what might have gone wrong and how can I now get the Pop3 service running, which in the above ISPConfig would change from Offline to Online.

Please see my nmap output below:-

root@aasai:~# nmap localhost

Starting nmap 3.93 ( http://www.insecure.org/nmap/ ) at 2005-10-22 20:45 BST

Please help me to get this one right.

Many thanks for your excellent article.

Why did you omitt courier? It's the best pop3 and mailserver for ISPConfig under DEBIAN?

As you can see in your nmap scan you currently have no pop3 and imap server installed.

Hi Till,

As far as I understood the steps, as described in the below section:

Postfix/POP3/IMAP

In order to install Postfix with SMTP-AUTH and TLS as well as a POP3 server that also does POP3s (port 995) and an IMAP server that is also capable of IMAPs (port 993) do the following steps:

and Also as mentioned in the Courier Section, which is described below:

Courier-IMAP/Courier-POP3

If you want to use a POP3/IMAP daemon that has Maildir support (if you do not want to use the traditional Unix mailbox format) you can install Courier-IMAP/Courier-IMAP-SSL (for IMAPs on port 993) and Courier-POP3/Courier-POP3-SSL (for POP3s on port 995). Otherwise you can proceed with the Apache configuration.

apt-get install courier-imap courier-imap-ssl courier-pop courier-pop-ssl

<- No


ipopd and UW-IMAP will then be replaced.

I thought Courier section is optional and if I want Maildir support or if I want the ipopd and Uw-IMAP servers to be replaced.

I thought I already have installed pop3 and pop3s as mentioned in the Postfix section, so why bother with Courier section.

So, is it not optional and should i do it now, will it work if I do it now, or should I start from the begining?

Many thanks,

Nandhu.

The Courier part is optional, you don't have to use it if you're happy with a POP3/IMAP daemon that uses mbox. If you want to have Maildir, then install Courier.

So you can

a) install Courier as per the instructions in the howto,

or

b) stay with your current setup and try to fix the POP3 problem. To do so, please have a look at /etc/inetd.conf and search for appropriate entries for POP3 and IMAP. You can also post your /etc/inetd.conf here so that we can see where the problem might be.

[nandhu]

Hi Falko,

Correct, that's what I thought too. And that's the reason I did not proceed further to install the optional Courier.

Basically I tried when I followed the tutorial 1st time, I ended up installing Courier and ISPConfig still showed me with POP3 Service alone as Offline, and so I reinstalled Kanotix from the begining and then started all from second time. So this time I thought I will not install the optional Courier Step to find out whether it will work out this time without Courier's involvement.

Yes, courier is optional but you wont get happy with an mbox based mailserver if you get more traffic on your server And that's what i told you above ....

Looks ok. Can you restart inetd:

/etc/init.d/inetd restart

and post the output of

netstat -tap

here?

I have done the same thing skipped this section. Now i have install the Qourier as per http://www.howtoforge.com/perfect_setup_debian_etch_p5

12 Courier-IMAP/Courier-POP3

Run this to install Courier-IMAP/Courier-IMAP-SSL (for IMAPs on port 993) and Courier-POP3/Courier-POP3-SSL (for POP3s on port 995):

apt-get install courier-authdaemon courier-base courier-imap courier-imap-ssl courier-pop courier-pop-ssl courier-ssl gamin libgamin0 libglib2.0-0

You will be asked two questions:

Create directories for web-based administration ? <-- No
SSL certificate required <-- Ok

What else do i need to do? Note: I already install ISPConfig and created some 3 web site.

Thanks,

[till]

Enable Maildir in ISPConfig under management > server > settings on the mail tab.

Hi Falko,

Excellent, after restarting the inetd it worked like a charm.

I think you should add a script to start mysql,inetd,bind9,apache2,proftpd,postfix automatically after reboot as part of your Perfect Setup. Its only a suggestion. I'm sure many linux/unix guys would know to do it straightway. But it would help many budding unix chaps like me.

Anyway, following is my netstat -tap after restarting, inetd, proftpd, bind9, apache, mysql and postfix :-

Do you think I can now go ahead and install Courier-IMAP/POP3 now as Till says it is the best to have.

Thanks Till for your suggesstion.

Thanks a lot to Falko and team for yet another tutorial.

I'm sure you can say that this debian sarge one works for Kanotix_RC11 as well. ))
