qmail

I am using Qmail and when I am sending mails I am sometimes getting the bellow error in my log for a particular domain.

Jun 22 05:20:47 221832-web1 qmail: 1308738047.397431 delivery 1040373: deferral: CNAME_lookup_failed_temporarily._(#4.4.3)/

Can anyone please tell me what are the factors responsible for such error ?

What are the DNS requests sent by Qmail when sending an email ?

FYI: The patch for the DNS cache size issue is already included in Qmail.

There seems to be an endless supply of messages in the Qmail maillog for a single address. Can anyone shed some light on why this might be and whether it is a problem? To me it looks like either spam or some sort of unhandled problem. It strikes me as unusual that the 'from=' field is blank. This… >>> More
