I would not trust RoadRunner. RoadRunner is AOL. AOL, Earthlink, Mindspring, RR, are all owned by AOL and are working with MAPS to block email at the IP level. This is an absurd attempt to stop spam mail because it blocks legitimate mail too. I cannot email any of their users, yet I have never spammed.

I've been able to circumvent the problem, but I've decided not to email those users anyway; doing so would be contributing to the censorship problem. It's an erosion of civil liberties. You guys should not be giving Road Runner your money.. you are contributing to the denial of service problem, even if they don't block your outgoing packets.

I have STILL been unable to find a work around for my problem. I even tried setting up postfix to relay my outgoing messages through my isp's smtp server with this command:

relayhost = smtp-server.mn.rr.com

But.. it still gets kicked back.

Here is the full message header of one of my messages that got bounced back:

Return-Path: <>
Delivered-To: pkinney@pwk.ath.cx
Received: by pwk.ath.cx (Postfix)

So it looks to me like it can't get out of my network for some reason, if I'm reading this correctly. Could someone please help me interpret this better? Perhaps offer some more troubleshooting tips? PLEASE?

Thanks in advance!

Post up any errors.

Cool

Here's what I got..

OK, connected to pwk.ath.cx...
< 220 pwk.ath.cx ESMTP Postfix
> HELO edit.dnsvr.com
< 250 pwk.ath.cx
> MAIL FROM:<pkinney@pwk.ath.cx>
< 250 Ok
> RCPT TO:<sput420@yahoo.com>
< 554 <sput420@yahoo.com>: Recipient address rejected: Relay access denied

Just for testing, send an email to me:
spam@masterc.no-ip.org

FYI: You don't have the ability to accept email for a yahoo.com domain unless of course you are within your own private LAN and then you can recieve it for whomever you'd like (BillGates@microsoft.com if it resolves fine). But sending mail to your server isn't going to recieve it for a yahoo.com ID. Well, not without some tweaking:
#relay_domains = $mydestination
relay_domains = $mydestination,yahoo.com

Remember to restart Postfix.

Cool

I get the same error with your email address:

OK, connected to pwk.ath.cx...
< 220 pwk.ath.cx ESMTP Postfix
> HELO edit.dnsvr.com
< 250 pwk.ath.cx
> MAIL FROM:<pkinney@pwk.ath.cx>
< 250 Ok
> RCPT TO:<spam@masterc.no-ip.org>
< 554 <spam@masterc.no-ip.org>: Recipient address rejected: Relay access denied

Ok, and does:
pwk.ath.cx
Resolve to your IP? Do you own that domain?
It's definitely something that doesn't ever get out of your network because I don't even see the connection in my logs.

Did you change the relay bit up there? Make sure it says:
pwk.ath.cx

Cool

It's mine.. through dyndns, and I agree, messages can come through to my server but outgoing messages don't seem to be able to get out. I can ping anything from the server which means dns "seems to be" working.. ugh, I just don't get it.

pwk.ath.cx does resolve to my ip - do an nslookup

thanks!

hmm..

Straight outta your postfix/main.cf from above:
# By default, Postfix relays mail
# - from "trusted" clients whose IP address matches $mynetworks,
# - from "trusted" clients matching $relay_domains or subdomains thereof,
# - from untrusted clients to destinations that match $relay_domains
# or subdomains thereof, except addresses with sender-specified routing.
# The default relay_domains value is $mydestination.

So you'll wanna make sure those things are set properly. Your 'mydomain' and 'myhostname' aren't even set, you'll wanna set those.

Cool

I will set those and restart postfix when I get home. I will post the results shortly.

Thanks again for your continued help MasterC, you are the man.

-sput

ok..

I added myhostname and mydomain, commented out the relayhost tag, and restarted postfix.

Still getting the same thing:

OK, connected to pwk.ath.cx...
< 220 ecstacy.pwk.ath.cx ESMTP Postfix
> HELO edit.dnsvr.com
< 250 ecstacy.pwk.ath.cx
> MAIL FROM:<pkinney@pwk.ath.cx>
< 250 Ok
> RCPT TO:<spam@masterc.no-ip.org>
< 554 <spam@masterc.no-ip.org>: Recipient address rejected: Relay access denied


Frustrating...

MasterC,

I was wondering, perhaps for testing purposes if you could allow my IP to relay mail through your smtp server, I wonder if that may work?

Let me know..

Thanks!

Will do!

I'll send you an email when it's all done.

Cool

Here is my current main.cf

postconf -n

alias_database = hash:/etc/postfix/aliases
alias_maps = hash:/etc/postfix/aliases
command_directory = /usr/sbin
config_directory = /etc/postfix
daemon_directory = /usr/libexec/postfix
debug_peer_level = 2
default_privs = nobody
inet_interfaces = all
mail_owner = postfix
mailq_path = /usr/bin/mailq.postfix
manpage_directory = /usr/share/man
mydestination = $myhostname, localhost.$mydomain
mydomain = pwk.ath.cx
myhostname = pwk.ath.cx
myorigin = $myhostname
newaliases_path = /usr/bin/newaliases.postfix
queue_directory = /var/spool/postfix
relay_domains = $mydestination
relayhost = [4.65.24.211]
sendmail_path = /usr/sbin/sendmail.postfix
setgid_group = postdrop
smtpd_banner = $myhostname ESMTP $mail_name ($mail_version)

I am really starting to think that my box is set up just fine.. I gotta be being blocked, I mean, could there even be another explanation?

And you've dropped all IPTables...

I'd have to guess 'yeah' but maybe not... Even if you are blocked, you should be able to relay through your ISP's mail server, unless they of course block themselves or relaying from unknown hosts (in which case though, I'd think that using your IP would work? , unless then they have only allowed specifically from a set of IP's they assign themselves..).

For kicks, see if you can setup postfix from the source tarball on www.postfix.org Alternatively, troubleshoot with another mail server ( Exim probably being the one I'd suggest first, and then Qmail ).

Cool
