[fetchmail]Posible bug, when couldn't find canonical DNS name

2001-09-28 17:05:38
Hi,

I found the following bug or misbehaviour (after a year of two of use):

Short description
=================
Today, when launching fetchmail, I get the error:

        telperion:~ # fetchmail -v
        fetchmail: couldn't find canonical DNS name of pop3.amenate.com

and exits after some seconds. That server is the last of the list, and no
server is polled. There is no syslog reporting.

Long description
================

The fetchmailrc file has not been modified, and worked a few hours
earlier. System has not been modified (it was switched of, it is my home
computer). It seems there is some kind of dns problem, as server
pop3.amenate.com does not resolve today. The entry for that mailserver is
the last in the list; however, fetchmail does not poll any of the other
servers, and writes nothing to syslog, just exits. If the entry for that
server is comented out, fetchmail works ferfectly - as has done for more
than a year - and polls all servers, fetching pending mail, as expected.

root .fetchmailrc file (called usually from ip-up), has the following
structure:

        set syslog

        poll SERVER1 with proto pop3 timeout 60
               user USERNAME, with password PASSWORD, is cer here

        poll SERVER2 with proto auto timeout 60
               user USERNAME, with password PASSWORD, is cer here

        poll SERVER3 with proto auto timeout 90
                user USERNAME, with password PASSWORD, is cer here

        poll pop3.amenate.com with proto auto timeout 30
               user "NUMBER", with password PASSWORD, is cer here


Version:

        telperion:~ # fetchmail -V
        This is fetchmail release 5.6.5+POP2+RPA+NTLM+SSL+NLS
        Linux telperion 2.4.2 #5 Tue Sep 25 12:20:02 CEST 2001 i586 unknown
        fetchmail: couldn't find canonical DNS name of pop3.teleline.es

I'm offline now. After connecting once:

        telperion:~ # fetchmail -V
        This is fetchmail release 5.6.5+POP2+RPA+NTLM+SSL+NLS
        Linux telperion 2.4.2 #5 Tue Sep 25 12:20:02 CEST 2001 i586 unknown
