[qmailtoaster] fresh installation smtp slow
Hello, Yesterday I installed a fresh Qmail Toaster box on Centos 5.4 according to wiki. The box works fine, but the SMTP is very slow. You have to wait about 30sec to send a blank message, no matter if you connect from LAN or from the internet. I have the same response if I telnet on port 25. Even if I telnet 127.0.0.1 25 I setup bind as caching-nameserver, no change. I tried with djbdns, no change. The server is behind an ADSL router with ports 22, 25 and 80 forwarded. I also tried putting the server in DMZ, no change. I out of ideas. I don't know where to look for the problem. Please give me a clue. Thanks!

Re: [qmailtoaster] fresh installation smtp slow
The reverse DNS is not set yet. Can this be a reason for the slow response? I.

My qmail-toaster is rejecting any e-mail with no reverse DNS record. Suggest you set it up ASAP. Regards Alex On 11/04/2010 10:20, Istvan Köpe wrote: The reverse DNS is not set yet.

Re: [qmailtoaster] fresh installation smtp slow
Hi there, Reverse lookup on your IP is not possible yet? That would be a VERY bad idea for any mail server. It is highly likely that in addition to slow performance, a lot of recipients would block your outgoing mails as phishing or spam.

Re: [qmailtoaster] fresh installation smtp slow
That sounds like something else then. Connect from localhost, at the very least, should be fast. Is there already a lot of traffic on the system? What's the load of the smtp process?

Re: [qmailtoaster] fresh installation smtp slow
I installed Centos minimal configuration, without any additional options selected. Than I installed only what is required to install according to wiki, with bind as caching nameserver. After that I installed QTP and ntop. I guess spamdyke is not part of default setup and I didn't install it. I looked at the logs in messages and smtp. Both are clean. I don't have errors, just delays. Where else should I look? What kind of additional info do you need, to be able to help? I.

You may have a RBL that is taking a long time to respond (or is timing out) that is causing the delay. If this started after installing Spamdyke, remove it until you can determine what the issue actually is. - Qmailtoaster is sponsored by Vickers Consulting Group (www.vickersconsulting.com) Vickers Consulting Group offers Qmailtoaster support and installations.
