some other posts also talk about a possible DNS problem....
(nslookup seems ok)
How do I check this?
"dig" (cli command) a few domains, and check the results.
That will tell you what server is being used.
for info my blacklists check is:
more /var/qmail/control/blacklists
-r zen.spamhaus.org
If you're using spamdyke installed by the qtp-install-spamdyke script,
the blacklists file (rblsmtpd) is no longer being used. Blacklists are
specified in spamdyke.conf file instead.
then it is
dns-blacklist-entry=zen.spamhaus.org
dns-blacklist-entry=bl.spamcop.net
When I comment these 2 lines, it's a bit faster : 10-12 sec (instead of 20-25
sec with the lines ) to have the Welcome message
With the dig command, I saw that only the second name server in
/etc/resolv.conf was used...
I put the 2nd line first in the /etc/resolv.conf ... and the Welcome message
comes directly....
There is probably a problem with this DNS...
All is OK now...
THX to all of you!
Yes, there was/is a problem with the nameserver you had specified in
/etc/resolv.conf. You really should have a resolver running on your QMT
host. If you don't, a simple way to get (a very good) one going is:
# yum install pdns-recursor
# chkconfig pdns-recursor on
# service pdns-recursor start
then add
nameserver 127.0.0.1
as the first line in the /etc/resolv.conf file.
That should get you going nicely.
P.S. Don't forget to uncomment out your blacklist entries in
spamdyke.conf. ;)
