Postfix package - relay access denied

Der-Tim

Hi there,

I recently installed the postfix package and configured it in a real quick-and-dirty way.

Just added the following configuration variables:

Listen Interfaces: loopback, LAN, OPT1 (NAT from external CARP-IP to localhost:25)
Custom main.cf: myhostname, smtp_helo_name (seem to be ignored totally)
Domains: 2 domains (domainA.tld, domainB.tld), both backed with the same mailserver IP
Recipients: tried it with nothing configured and manually configured in these ways => domainA.tld OK, domainB.tld OK, @domainA.tld OK, @domainB.tld OK, username@domainA.tld OK, username@domainB.tld OK
AccessLists: mynetworks (local network and one CIDR I can trust)
Antispam: Header Verification Basic

But I always get an "relay access denied"-error.

<snip>telnet aa.bb.cc.dd 25
Trying aa.bb.cc.dd…
Connected to aa.bb.cc.dd.
Escape character is '^]'.
220 <wrong hostname="">ESMTP Postfix
helo host.domain.tld
250 <wrong hostname="">mail from: user@domain.tld
250 2.1.0 Ok
rcpt to: username@domainA.tld
554 5.7.1 username@domaina.tld: Relay access denied
quit
221 2.0.0 Bye
Connection closed by foreign host.

What am I doing wrong? Maybe I'm actually blind... ;-)

Thanks for any advice.

Best regards, Tim/username@domaina.tld</wrong></wrong></snip>

Include your internal smtp servers on MyNetworks field at package Access List tab.

Hi,

thanks for your answer. That's what I already tried, but had no success. :-(

Any other idea?

The wrong SMTP info was just a telnet sample or an error you are getting always?

Enable postfix logging and check if it alerts any missing/wrong configuration.

Hi there,

I just enabled the logging to /var/log/maillog but the file stays empty. Even after a stop and start of the service.

Here's my main.cf:

Any idea?

smtp port is listening but no mail is going through postfix?

Do you have a nat rule on same port forwarding it direct to internal mail server?

Or are you on nanobsd?

Der-Tim

Hi,

as I said before, connection is established to the postfix running on the pfSense. There's only one NAT-rule from CARP-IP:25 to localhost:25 for using a virtual IP. The virtual IP isn't used in another way.

I'm running it on an amd64 system.

what version of pfsense are you using? if it 2.1_x64, you need to copy /usr/local/etc/postfix files to /usr/pbi/postfix-amd64/etc/postfix as the config reads from the old location. you can see where the config file is reading in main.cf. it's the first line above #main.cf\ and is most likely /usr/local/etc/postfix/main.cf
you will need to do this every time you do an upgrade until marcelloc does the fix

I also had issues until i placed 2,6s into the greet time under antispam.

Thanks, that did the trick! :-)
