Question : Qmail

I tried setting up qmail and managed to mess it up. So I started all over and more carefully followed the web site "life with qmail". Now I can telnet port 25 from the qmail box and from a different computer, and I can send and receive using telnet to two test users. Next I wanted to setup the pop portion of qmail. So according to "life with qmail", I downloaded the checkpassword program and untarred it, then ran make. I got an error
"/usr/bin/ld: errno: TLS definition in /lib/libc.so.6 section .tbss mismatches non-TLS reference in checkpassword.o /lib/libc.so.6: could not read symbols: Bad value collect2: ld returned 1 exit status make: *** [checkpassword] Error 1"
I think I found that I have to install a patch called "checkpassword-0.90.errno.patch" but when I try to find this patch, the links usually point me to something like this
"diff -u checkpassword-0.90.old/error.h checkpassword-0.90/error.h
--- checkpassword-0.90.old/error.h  2000-12-23 00:40:46.00000000 -0600"
and so on. I have no idea how I'm suppose to get or install this patch. I usually get a .tar file, untar it and run make, make install. My best guess from the links I found for the checkpassword patch is I have to edit a file? and put in the diff -u checkpassword..... in some file?
Basically, I don't know for sure if the checkpassword patch is what I need, and how to install it.

Answer : Qmail

Ok,

The mail client needs two things:

1- smtp server that it can send messages to send them out (for users on the same smtp server or outside domains)

2- POP3 or IMAP4 server to connect and read / manipulate received messages on the server for the user mail box.

So, if your smtp server is up and running and reachable the mail client can connect to and send messages out. smtp server can not be used to retrieve messages from the mail box.

The message you see for the imap, could be due to

- wrong setting in outlook (wrong server name / ip address)
- the server is not reachable on IMAP4 port (could be a firewall on the network denying you or firewall on the linux box - check iptables rules)
- the IMAP4 server on the linux box is down or mis configured
