TEMP_FAILURE: DNS Error: Timeout while contacting DNS servers when receiving emails
A little under a week ago, receipt of emails from external sources stopped working on the Fedora Core 4 system.
The error returned is:
TEMP_FAILURE: DNS Error: Timeout while contacting DNS servers
The DNS works - internet access for browsers etc still works.
Evolution works to retrieve emails from external POP3 servers.
Internal email (ie an email sent from the server machine) works, as does the aliasing (redirecting the mail to another address).
It is not just that no external email is able to be received by the system.
More information can be provided if necessary.
Thanks in advance
