Hugh replies:

Thanks for the reply; here goes:

hlawson@desktop:~$ fetchmail -vv

fetchmail: 6.3.9-rc2 querying pop-server.triad.rr.com (protocol POP3) at
Fri 08 May 2009 09:50:07 AM EDT: poll started

fetchmail: getaddrinfo("pop-server.triad.rr.com","pop3") error: Name or
service not known POP3 connection to pop-server.triad.rr.com failed: No
such file or directory

fetchmail: 6.3.9-rc2 querying pop-server.triad.rr.com (protocol POP3) at
Fri 08 May 2009 09:50:22 AM EDT: poll completed

fetchmail: Query status=2 (SOCKET)

fetchmail: normal termination, status 2


Occasionally fetchmail connects; the same is true with emacs
gnus. Moreover the 'host' command works as expected.  

$ host pop-server.triad.rr.com
pop-server.triad.rr.com has address 71.74.56.73

Now if I put '71.74.56.73' in the .fetchmailrc in place of
'pop-server.triad.rr.com'  I get this in return:

$ fetchmail -vv

fetchmail: 6.3.9-rc2 querying 71.74.56.73 (protocol POP3) at Fri 08 May
2009 10:01:55 AM EDT: poll started
Trying to connect to 71.74.56.73/110...connected.
fetchmail: POP3< +OK POP3 server ready.

fetchmail: POP3< +OK please send PASS command
fetchmail: POP3> PASS *
fetchmail: POP3< +OK hlawson is welcome here
fetchmail: selecting or re-polling default folder


and so on, a normal reply.  With the IP service is very fast. With the
name, there is a delay of 20 seconds or so before error
message.
