Hello rajesh
I had the same problem as you...
I´ve done these things:
- In /var/qmail/control/blacklists I remove all the blacklist urls and put
only one: bl.spamcop.net
- My distro was Fedora 4 with the new (from them) kernel 2.6.17 and I got a
lot of problems with out of memory and other things... see the attached
file..what I do is just backup the kernel 2.6.16...Now, everything is OK....
the slow smtp stoped...
I don´t know if this gonna helps you...but i´ve solved the problems here
with it...see your DNS... like other guys says...
regards
thiago

Subject: Re: [qmailtoaster] SLOW SMTP SESSION
hi
both m/c are dell dual xeon 2.8 with 2 gb ram
ips below are allocated for dns server by our isps.
the slow machine is slow at the third stage ie sending message. it is fast
during the stages -- connecting, authorizing
slow machine -- bocacom, florida
nameserver 127.0.0.1
nameserver 199.237.48.5
nameserver 199.237.48.6
fast machine -- theplanet, texas
nameserver 127.0.0.1
nameserver 216.234.234.30
nameserver 70.84.161.10
nameserver 70.84.160.10

hi
both machines use normal port 25
/var/qmail/control/blacklists could be the difference then. Are these
files
the same on both machines?
however i noted one more point
on the second machine when we send email to some domain within the same
machine then it is fast.
That's to be expected. qmail-send passes the message off to qmail-local
instead of qmail-remote. Sounds like qmail-remote is where the
sluggishness
is. This doesn't make sense though, as the smtp session of the sender (MSA
session) is complete by that point.
mails to email ids on remote domains is slow in the "sending message"
stage
This is sounding more like a DNS problem. I'm guessing now that it's slow
looking up MX records of recipient domains.
Is there a DNS cache working on each machine?
What's in the /etc/resolv.conf in both?
also i have one more question -- is it possible to disable spam scanning
for mail submission. i do not wish scan my authenticated users for spam,
however i wish to maintain virus scanning
TTBOMK, that's the way the toaster presently operates. When a client
authenticates, RELAYCLIENT is set (which I'm guessing tells simscan not to
scan for spam?). You should see this reflected in the smtp log.
It'd be good to have your clients use port 587 for submission if that's
feasible.
thanks

hi
we have two different type of installations of qmail toaster on two
different machines
m/c 1
redhat enterprise 3
qmailtoaster without using db for vpopmail
m/c 2
fedora 4
qmailtoaster using mysql mysql 5 db for vpopmail
both m/c are enabled in the same way with smtp authentication and
checks for virus / spam before sending emails by domains hosted on the
servers
we find that in m/c 2
while using outlook express there are three stages
1) connecting
2) authorizing
3) sending message -- slow
the speed of smtp sessions for the first two stages are similar in
both machines but in the third stage the m/c 2 takes around 7 seconds
where as the m/c 1 sends the message instantly.
this delay gets troublesome for clients who use mail exchangers for a
large no of email ids.
any idea what the reason could be ?
rajesh mahadevan
RBLs?
Is either machine using submission (587) port?
Is /var/qmail/control/blacklists the same on both?
