Unable to send/receive email
 

I have installed qmail on RH 8.0 using www.ndhsoft.com/qmailtoaster.htm
Everything was flowing smoothly until the past few days :-(

A couple of days ago, users were able to send/receive email locally, but not remotely. Now, we are unable to send nor receive emails locally and remotely. Here is a snippet of the /var/log/qmail/smtp/run file: (We are seeing this message repeatedly)

Also, here is a snippet of our /var/log/qmail/send/run file:

Any suggestions?



Thanks in advance.

chroot
 

I have had problems with similar symptoms with other programs after install or upgrade, and in many cases (especially when some daemon cant find a bunch of files) it is because the daemon or program runs chrooted (doen't have acccess to entire filesystem)

so: Check if the process is chrooted, and if it is, try switching it (chrooting) off, and see if it helps

just a suggestion.

good luck

I resolved the errors in /var/log/qmail/smtp/run, and users can send email to external accounts now, but I still see the same errors in /var/log/qmail/send/run . Any suggestions on how to get rid of the "cname" errors?
