Last Wednesday CableOne (my ISP (unfortunately))
suffered a violent thunderstorm at their headquarters
in Arizona. All CableOne internet customers were
without Internet for about six hours. Ever since the
internet became available again my mail server has not
been able to send mail from espersunited.com to
yahoo.com, gmail.com and possibly more. My mail
server attempts to deliver the outgoing email, but
returns the mail to the user who sent it with an error
message. The interesting thing is that I can ping the
address of the recipient mail servers at Yahoo and
Gmail, but I cannot telnet to their port 25. I don't
know if this is my problem or theirs, and if it is
theirs I don't know how to notify them of it.
CableOne assigns all addresses (including their DNS
servers) through DHCP. Is there a way to query my
router for DNS information and use that instead of the
two hard-coded IP addresses in /etc/resolv.conf? Here
is the /etc/resolv.conf file on my server box:
domain espersunited.com
nameserver 192.168.1.1
nameserver 24.116.0.160
nameserver 24.116.0.202
The 192.168.1.1 is the address of my router. I don't
know if the other two addresses are still valid. I
know that the Gentoo LiveCD has some way of finding
what these IP addresses should be, but I don't know
how it does it. Can anyone help me with this? Also
any insight into my outgoing mail problem would be
greatly appreciated...
