Can't send without relayhost?

[kusumoto]

I am using postfix on an ubuntu 9.10 server. It is working perfectly on all parts of postfix/dovecot. I have it set up to forward through my router and there are MX and A records in my primary DNS server for the mail server. The mail server also has a DNS server (forwarding requests it can't answer to the primary DNS server).
I commented out 'relayhost =' in my main.cf
I don't want to use a relay host. I want to send out directly.

Whenever I try to send to a domain other than the one hosted by the mailserver, I get an error stating.
The mail server responded: 5.7.1 <email i was sending to>: Relay access denied. Please check the message recipient <email i was sending to> and try again.

Please assist.

Yes, you can send emails without relay.
Look, one thing is relayhost, per example another smtp and relay is for accounts out of your domain, i think.

I don't want to use relay.
It seems to be trying to do that anyway.
That's what the issue is.

If you have a dynamic IP, this IP is most likely blacklisted, and you must relay through another mailserver: http://www.howtoforge.com/postfix_re...her_mailserver

You can check if your IP is blacklisted: http://mxtoolbox.com/blacklists.aspx

I have a static IP and it is not blacklisted. The DNS entries on the external DNS server points to my router. My router forwards all www/pop3/smtp traffic to/from the internal static of my mail server.

I would think this is a software issue, rather than a networking issue. That being said, I am open to any other ideas.

Did you enable "Server requires authentication" in your email client?

[kusumoto]

I didn't have that enabled, but when I tried sending to the other domain with that enabled I still got the same error.

Any errors in your mail log?

[kusumoto]

This is the log from the send attempt.

Feb 5 09:14:00 mail dovecot: auth(default): new auth connection: pid=21297
Feb 5 09:14:05 mail postfix/smtpd[21298]: connect from gatewayhostname[myip]
Feb 5 09:14:05 mail postfix/smtpd[21298]: NOQUEUE: reject: RCPT from gatewayhostname[myip]: 554 5.7.1 <targetemail>: Relay access denied; from=<sourceemail> to=<targetemail> proto=ESMTP helo=<sendershostname>
Feb 5 09:14:05 mail postfix/smtpd[21298]: disconnect from gatewayhostname[myip]


EDIT: put in some variables because i'm paranoid

I did a quick SMTP Diagnostic on your IP and I do see that you are receiving one warning about your rDNS. This might not be the cause of your mail problems but it definitely isn't helping. Large ISPs like Gmail or Hotmail may deny your mail or flag it as spam since your rDNS doesn't match.

I would recommend resolving that and then seeing if that helps.

Thanks,
