Ole,

Where does the stall occur?  Before the server sends its greeting, or
afterwards?

If the stall happens before the server sends its greeting, your problem
is likely to be DNS.  The server attempts to perform a reverse DNS
lookup on the IP address you are connecting from.  If your DNS is
misconfigured, it will cause this step to go (VERY) slowly.


telnet mail.domain.tld 110
Trying xxx.xxx.xxx.xxx...
Connected to mail.domain.tld.
Escape character is '^]'.
+OK <[EMAIL PROTECTED]>   <==== server greeting
user [EMAIL PROTECTED]
+OK
pass 12345
-ERR authorization failed
Connection closed by foreign host.


Generally, your '/etc/resolv.conf' file should have your localhost IP
address (or 0.0.0.0, you choose) as the first line, followed by your
forwarders, like so (where xxx.xxx.xxx.xxx are the IP addresses of other
nameservers).

nameserver 127.0.0.1
nameserver xxx.xxx.xxx.xxx
nameserver xxx.xxx.xxx.xxx


I always modify the '/etc/hosts' file as well, to put the FQDN of the
server on a line with its own IP address (not localhost's IP address),
like so:

# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1               localhost.localdomain localhost
xxx.xxx.xxx.xxx         mail.domain.tld mail



If the stall happens after you submit your username and password, the
problem lies elsewhere.  Where --- I don't know.


Sincerely,

Subject: Re: [qmailtoaster] slow pop login

Hello,

I got the same problem,

hw/sw:
fujitsu-siemens xeon server.
2x250gb hw raid-1
1GB ram
Centos 5 installed as QT advises
QT installed successfully with djbdnscache

everything works except 60seconds+++ for login via pop3 ( telnet LAN-IP
110 )
If i do telnet localhost 110, it answer as it should.

Iptables and Selinux is disabled.

But POP3 with SSL works as it should.

Ideas?

B/R Ole Johansen
