I have a Debian machine running Exim4.
However, when checking the Exim log, I noticed this issue when mailing my own domain:
2010-12-14 09:20:01 1PSQ77-0005mG-9w ** root@domain.com: all relevant MX records point to non-existent hosts
2010-12-14 09:20:01 1PSQ77-0005mJ-CH ** root@domain.com: all relevant MX records point to non-existent hosts
And when checking MX in dig:
# dig mx domain.com
...

Yet I am able to ping and telnet the Barracuda server:

Any clue what might cause Exim to spit out those errors?
Thanks
