Sorry, having a busy life

Please also check for the presence/contents of:

/etc/host.conf (Redhat, Debian)
/etc/nsswitch.conf (Redhat, Debian)
/etc/resolv.conf
/etc/named.conf

And there might be a file named .hosts somewhere but i'm not sure. Either way, check to make sure everything that relies on DNS (Postfix, Sendmail, fetchmail, whatever) is using the same updated configuration for your situation.

It seems to me that all the configuration files are OK. I'll post them in case I'm missing something.

host.conf:
Code:
order bind,hosts
nsswitch.conf:
Code:
#
# /etc/nsswitch.conf
#
# An example Name Service Switch config file. This file should be
# sorted with the most-used services at the beginning.
#
# The entry '[NOTFOUND=return]' means that the search for an
# entry should stop if the search in the previous entry turned
# up nothing. Note that if the search failed due to some other reason
# (like no NIS server responding) then the search continues with the
# next entry.
#
# Legal entries are:
#
#       nisplus or nis+         Use NIS+ (NIS version 3)
#       nis or yp               Use NIS (NIS version 2), also called YP
#       dns                     Use DNS (Domain Name Service)
#       files                   Use the local files
#       db                      Use the local database (.db) files
#       compat                  Use NIS on compat mode
#       hesiod                  Use Hesiod for user lookups
#       [NOTFOUND=return]       Stop searching if not found so far
#

# To use db, put the "db" in front of "files" for entries you want to be
# looked up first in the databases
#
# Example:
#passwd:    db files nisplus nis
#shadow:    db files nisplus nis
#group:     db files nisplus nis

passwd:     files
shadow:     files
group:      files

#hosts:     db files nisplus nis dns
hosts:  dns files

# Example - obey only what nisplus tells us...
#services:   nisplus [NOTFOUND=return] files
#networks:   nisplus [NOTFOUND=return] files
#protocols:  nisplus [NOTFOUND=return] files
#rpc:        nisplus [NOTFOUND=return] files
#ethers:     nisplus [NOTFOUND=return] files
#netmasks:   nisplus [NOTFOUND=return] files     

bootparams: nisplus [NOTFOUND=return] files

ethers:     files
netmasks:   files
networks:   files
protocols:  files
rpc:        files
services:   files

netgroup:   nisplus

publickey:  nisplus

automount:  files nisplus
aliases:    files nisplus

maine.rr.com and 24.92.226.9 are the addresses you need for proper DNS resolving?

Well, originally Fedora setup my resolv.conf to search maine.rr.com and have 192.168.0.1 (currently my router) as the nameserver. After that wasn't working, I changed the dhclient-script so that it would always use 24.92.226.9 (which my ISP gave to me) as the nameserver, but I never changed the search domain.

I'm having trouble finding a good solution here, Mail and DNS aren't quite within my general field of knowledge just yet to the point where I can tell you exactly where your problem lies at the moment.
I'm hunting around for articles that are similar to your problem but haven't found an exact match yet.

In the meantime please check these links and compare to your own settings where possible:
http://www.linuxquestions.org/questi...ora+DNS+Server
http://www.linuxquestions.org/questi...ora+DNS+Server
http://www.linuxquestions.org/questi...ora+DNS+Server
http://www.yourhowto.org/content/view/36/9/
http://www.yourhowto.org/uploads/serversetup/
http://www.howtoforge.com/taxonomy_menu/1/8
http://www.tldp.org/HOWTO/DNS-HOWTO-5.html
These should have settings listed you can find and review on Fedora Core. Since your problem right now still circles around not being able to send, but are able to receive; it's clear that machines on the outside (Internet) can find your machine just fine, but your machine is having a problem finding a good route towards the outside. If that's really a DNS issue then the above might help pinpoint the problem in your DNS settings and provide a bit more information for the future.
Asking perhaps in abundance, but your server machine can reach other known mail servers through a simple ping for example?
Are your static routes also still correct?
