Hi list, i have a problem with pop3 connections. Suddenly the outlook and
thunderbird clients were very slow.



I'm do not know where to begin testing.



I tried what sources:



FROM localhost



# telnet mail.mydomain.com 110

Trying 127.0.0.1...

Connected to localhost.localdomain (127.0.0.1).

Escape character is '^]'.

+OK ***@mail. mydomain.com
<mailto:***@mail.%20mydomain.com>



Responds very fast



FROM other computer in the LAN



# telnet mail.mydomain.com 110

Trying 172.16.0.2...

Connected to 172.16.0.2 (172.16.0.2).

Escape character is '^]'.

//wait about 15 sec, and then answer

+OK ***@mail. mydomain.com
<mailto:***@mail.%20mydomain.com>





Any idea???



Very thanks.

HI

Most likely DNS and reverse lookup options in the tcp server scripts



I have had the same problem with other services started under tcpserver and
this may help you

The -H, -R options are quiet important.

Look at http://cr.yp.to/ucspi-tcp/tcpserver.html





The pop3d run file:



#!/bin/sh

PATH=/var/qmail/bin:/usr/local/bin:/usr/bin:/bin

export PATH

exec tcpserver -H -R -v -c100 0 110 qmail-popup mail.server.com \

/usr/home/vpopmail/bin/vchkpw qmail-pop3d Maildir 2>&1

I'm check in /var/qmail/supervise/qmail-pop3d/run, and the file contain



#!/bin/sh

PATH=/var/qmail/bin:/usr/local/bin:/usr/bin:/bin

export PATH

exec tcpserver -H -R -v -c100 0 110 qmail-popup mail.mydomain.com \

/home/vpopmail/bin/vchkpw qmail-pop3d Maildir 2>&1



According to what you say, is okey.
