Upgrade Issue

[pillerk]

Hi
Someone already solved this problem? (no such server mail.example.org during upgrade)
I have problems with the 6.0.5 from 5.0.22 to upgrade.
Thanks

Okay; so onto your problem. Please post the following

cat /etc/hosts
cat /etc/resolv.conf
dig yourdomain mx
dig yourdomain any
host `hostname` < - note backticks and not single quotes
