SMTP still slow..even after -Rt0

[dourtyb]

Running RHEL 3.0, plesk 7.5.4. I still seem to be getting a 25-30sec delay making an SMTP connection even with -Rt0 added to smtp_psa and smtps_psa. Here is the complete args line:

server_args = -Rt0 /usr/sbin/rblsmtpd -r sbl-xbl.spamhaus.org /var/qmail/bin/relaylock /var/qmail/bin/qmail-smtp
d /var/qmail/bin/smtp_auth /var/qmail/bin/true /var/qmail/bin/cmd5checkpw /var/qmail/bin/true

Any ideas? I did restart xinetd after editing the file.

Thanks,

Brian

Brian, did you solve this issue? I also made the suggested -Rt0 tweek and still no luck.

Thanks

Yes, I resolved the issue. Unfortunatly I'm not 100% sure how I did it. After applying the latest RedHat updates and rebooting it cleared up. Have you tried a reboot?

bingo! ordb.org is down, although i think i saw an article about them shutting down or something.

remove any reference of ordb.org from your rbl lists.

GREAT info

Hi,

You solved a problem thats been dogging us for three days now.

Why on outbound is spam checked?

If you are ever in the UK I will also buy you a bear (although bear trading is illegal here!)..... probably best to have a beer - lol. (Marlon, sorry but it was a funny typo ).


Regards

Chris

Yes , we don have bear in Baja California jajaja ,

The outbound SMTP checks for ip's in spammer's black list .

This problem popped up on my server as well and caused 450 timeouts from verizon.net. What a pain in the *** this was to troubleshoot. How did you figure out to check ordb.org?

Also on that note, which of the rbl orgs are the ones worth keeping in there? I use -r sbl-xbl.spamhaus.org -r bl.spamcop.net -r multihop.dsbl.org
