Re: DNS bug: CNAME_lookup_failed_temporarily
For whatever it is worth: I started having the same problem with hotmail on Friday (could have started before then, but I know it was happening Friday), I am running the latest qmail-ldap (which has the dns patch). I have sent email to hotmail from the same box in the past. I sent some email from the server at work (exact some setup) and they went through fine. I am not sure why this problem just came up out of no where, the only thing I could figure would be that I only have 32MB of RAM and I have had a few minor problems with qmail-ldap dealing with the low amount of RAM in the past (although my swap is hardly ever used). In any event I had been planning on installing dnscache on the machine anyways, so I did and the problem went away after that. I doubt that the above information will be of much use, but I thought I would just throw it out since we had near to the same problem with the same domain.

My request should have been for hotmail. Thanks for realizing my mistake. (I always mix those two up -- giant free email service that causes lotsa problems). 4.dnsqr mx hotmail.com have result: 15 hotmail.com: 504 bytes, 1+12+5+8 records, response, noerror query: 15 hotmail.com This result is what I expected. hotmail intentionally keeps their MX response to under 512 bytes to avoid problems with, e.g., qmail. Your recursive resolver appears to provide the same additionals as a direct query to hotmail's ns (dnscache does not, which was why I asked for the dnsq output). So, now that Greg has his domains straight, we've proven that: 1. Your server successfully looks up hotmail's MX records. 2. The patch to qmail was unnecessary (but should not be a problem). Odd. Can we please get: qmail-showctl (unedited, please) and some log file snippets, from mail creation/injection to delivery attempt, of a failed hotmail delivery? -- Greg White
