Ahmad,
Without reading your message in detail, this sounds like
one of the FAQs - checkout the -H, -R and -l (That's a
lower-case L) options to tcpserver: Your system is
probably failing on ident or DNS lookups.
Dig around in the archives for more info (keywords:
slow, tcpserver).
cheers,
Andrew.

Subject: Slow SMTP and POP3 response (sorry, it's a long one)
-----BEGIN PGP SIGNED MESSAGE-----

Dear All,
We're currently migrating our server from sendmail+inetd (on Linux kernel
2.2.13) to qmail+tcpserver.
It's generally done except for one thing. The SMTP and POP3 response is
much slower than before.
What I mean by slower is about 50 seconds to nearly 2 minutes. It's not
acceptable to most of our users.
The server is meant to provide mailing service to local network. Following
are the logs showing the fact.

I know that this is an FAQ but before flaming me please take a look what
I've tried to do.
Here are my configuration (basically following LWQ):
Output of qmail-showctl (some are deleted but they are just default ones):
qmail home directory: /var/qmail.
user-ext delimiter: -.
paternalism (in decimal): 2.
silent concurrency limit: 120.
subdirectory split: 23.
user ids: 7790, 7791, 7792, 0, 7793, 7794, 7795, 7796.
group ids: 2108, 2107.
bouncehost: (Default.) Bounce host name is lsi.ipb.ac.id.
concurrencylocal: (Default.) Local concurrency is 10.
concurrencyremote: (Default.) Remote concurrency is 20.
databytes: (Default.) SMTP DATA limit is 0 bytes.
defaultdomain: Default domain name is ipb.ac.id.
defaulthost: (Default.) Default host name is lsi.ipb.ac.id.
helohost: (Default.) SMTP client HELO host name is lsi.ipb.ac.id.
idhost: (Default.) Message-ID host name is lsi.ipb.ac.id.
localiphost: (Default.) Local IP address becomes lsi.ipb.ac.id.
locals:
Messages for localhost are delivered locally.
Messages for lsi.ipb.ac.id are delivered locally.
Messages for perpus.ipb.ac.id are delivered locally.
Messages for pustaka.ipb.ac.id are delivered locally.
me: My name is lsi.ipb.ac.id.
plusdomain: Plus domain name is ac.id.
rcpthosts: (Default.) SMTP clients may send messages to any recipient.
perpus.ipb.ac.id and pustaka.ipb.ac.id are not yet registered to the
machine (202.159.95.54) but lsi.ipb.ac.id is.
Relaying is controlled by tcpserver
/etc/tcp.smtp
202.159.95.54:allow,RELAYCLIENT=""
127.:allow,RELAYCLIENT=""
10.:allow,RELAYCLIENT=""
qmail-smtpd and qmail-popup use tcpserver and supervise
/var/qmail/supervise/qmail-smtpd/run
#!/bin/sh
QMAILDUID='id -u qmaild'
NOFILESGID='id -g qmaild'
MAXSMTPD='cat /var/qmail/control/concurrencyincoming'
exec /usr/local/bin/softlimit -m 2000000 \
/usr/local/bin/tcpserver -v -p -R -H -x /etc/tcp.smtp.cdb -c 20 \
-u 7791 -g 2108 0 25 /var/qmail/bin/qmail-smtpd 2>&1
/var/qmail/supervise/qmail-smtpd/run
#!/bin/sh
exec /usr/local/bin/softlimit -m 2000000 \
/usr/local/bin/tcpserver -v -R -H 0 110 /var/qmail/bin/qmail-popup \
lsi.ipb.ac.id \
/bin/checkpassword /var/qmail/bin/qmail-pop3d Maildir 2>&1
As you can see I have tried using both options -R and -H which are usually
advised for this kind of problem.
Our qmail start script is basically using the LWQ version with minor change
to incorporate pop3d using supervise
|#!/bin/sh
- --deleted--
pause)
- --deleted--
echo "Pausing qmail-pop3d"
svc -p /var/qmail/supervise/qmail-pop3d
;;
cont)
- --deleted--
echo "Continuing qmail-pop3d"
svc -c /var/qmail/supervise/qmail-pop3d
;;
restart)
- --deleted--
echo "* Restarting qmail-pop3d"
svc -u /var/qmail/supervise/qmail-pop3d
;;
- --deleted--
exit 0
I apologize for the length of this message but we're a bit stuck here.
Thank you
in advance.
Regards,
Ahmad Ridha
