Title: fetchmail DNS failure
Post by: Brian Read on December 31, 2002, 03:45:14 PM

I'm getting this:

fetchmail: couldn't find canonical DNS name of mail.cix.co.uk
all mailserver name lookups failed, exiting

Despite the /etc/fetchmail has no mention of the "mail.cix.co.uk" as I have replaced it with the IP address.

any ideas?

cheers

Sorry, ignore this, the error was from the "other" server which had not been editted. All the same I can't see why the lookup is now failing when it has worked for almost a year!!

cheers

You've never known anyone to break their DNS configuration?

I can 'ping' the name fine, so I guess that means that the DNS entry is ok.  It just fails (now) in fetchmail (on both servers), when it worked up to about a 2 days ago.
I did switch one server from Server to Server+Gateway, which means i am now using the SMEserver internal DNS, rather than the one on the Ipcop firewall.

check your templates - are you using multipop ?

make sure there is a line
$OUT .= " no dns \n";

right after the protocol line.

Fetchmail is performing dns queries on all addresses in the email headers and barfs if it cant resolve them all.

I am and have added the 'no dns' to the template and that seems to have worked.  The templates I am using are generated by Stephen Noble's multiple mailbox contribution, so he needs to add that to his distributed code - are you there stephen?
