Qmail SMTP lag even with -Rt0

[jungleboy]

Guys help!

Spent around more than 3 hours on that and cannot make it running. It is the common problem with the lag when an e-mail client connects to Qmail SMTP. The server is waiting 30 seconds or more and then displays the welcome message. The problem is that most e-mail clients give up during this time and its very annoying.

I am running Plesk 8.0.1 on Fedora core 4

Before you ask :

- yes ive added -Rt0 as first argument for server args in both /etc/xinetd.d/smtp_psa and /etc/xinetd.d/smtps_psa

- no, i am not running any anti-spam software, no MAPS , no SPF, no spam assasin - nothing

- yes, i disabled dr. web

- yes the problem is only when a remote user connects to my server (if i am connecting from localhost it works rapidly)

The server is not under heavy load , I have only ~20 e-mail accounts on it and several domains. Ive read half of the internet and everybody talks about -Rt0 which is the magic here - but its not in my case

I have the same problem, SMTP takes ages.

I tried the -Rt10 as well and no luck.

This looks like a dns issue, please check /etc/resolv.conf if data is correct (nameservers). Probably there is a nameserver in resolv.conf which isn't very responsive, please remove or change!

How can I test which one is going slow?
They all seem correct to me, although I'm not sure about the search line:

; generated by /sbin/dhclient-script
search onlinehome-server.info

onlinehome-server.info is the domain of the hosting company I use but my domain is different, obviously. What should it be?

 

[pdreissen]

Can you post the complete resolv.conf please, are you having your localhost dns in it ? nameserver 127.0.0.1

Hi, sorry it has taken me so long to reply, my resolv.conf has the following lines:

search onlinehome-server.info
nameserver 87.106.9.251
nameserver 195.20.224.234
nameserver 195.20.224.99

None of them are my servers IP address. onlinehome-server.info is a 1&1 address so not sure if that is correct.

Thanks

Paul

I have the same name servers and I am also hosted by 1&1 and I have smtp lag as well.

Its actually not my SMTP thats lagging. People get e-mails from my server instantly, its the delivery of messages to users boxes, how can I speed this up?
