It'd be interesting to see if an upgrade took care of this. Wouldn't take much. # qmailctl stop (Make sure it's really stopped and not in the middle of a send) # qmailctl stat # yum upgrade qmail # qmailctl start 5 minutes at most. On 11/30/2017 7:59 AM, Jeff Koch wrote: I don't think I

The server connects to a BIND DNS server. However, this CNAME issue apparently has been a problem for a long, long time as noted in the link Eric provided. Jeff On 11/30/2017 9:55 AM, Chris wrote: Is the server that is having the issues using djbdns or BIND?  There was a thread on June 21

I'll see if I can have a patched version for separate download out tomorrow. It's interesting that I never see these errors on my servers. How often do you see them, and is mail not delivered? On 11/29/2017 9:24 PM, Jeff Koch wrote: Hi Eric: I read the link you provided and agree with the
