I am building a server using this config -> http://www.purplehat.org/?page_id=4 and when trying to test basic email capabilities I get -> NOQUEUE: reject: RCPT from when try to send a test email.

Below are my related configs

How to I get postfix to send emails?

UPDATE 2/14/2015 1430 EST

Verbose logging output:

https://bpaste.net/show/6a2a70cb2ab5

By setting test computer IP to mynetworks = IP, You can see mail getting much farther through the system, but then chokes match classes. How do I force Postfix to match 0.0.0.0 any IP source /and destination domain?

  • Neither from or to domains are local or configured as relay domains, therefore you get a relaying denied error – Dan Feb 13 '15 at 19:27

FYI, 454 4.7.1 <someemail@example.com: Relay access denied; was the result of defer_unauth_destination. It's slightly different with reject_unauth_destination, with reject means permanent error with code 550 and defer means temporary error with code 450.

But wait..., I don't have any parameter that use defer_unauth_destination. Where does the weird restriction come from?

Actually, postfix has one hidden restriction parameter called smtpd_relay_restriction. It is new feature so older tutorial may not covers it. By default, smtpd_relay_restriction has value

# postconf smtpd_relay_restriction
permit_mynetworks, permit_sasl_authenticated, defer_unauth_destination

So, that explains where the defer_unauth_destination

But it didn't answered my question about my client getting rejected :(

The behavior of (defer|reject)_unauth_destination was documentation in postfix manual pages.

reject_unauth_destination

Reject the request unless one of the following is true:

  • Postfix is mail forwarder: the resolved RCPT TO domain matches $relay_domains or a subdomain thereof, and contains no sender-specified routing (user@elsewhere@domain),
  • Postfix is the final destination: the resolved RCPT TO domain matches $mydestination, $inet_interfaces, $proxy_interfaces, $virtual_alias_domains, or $virtual_mailbox_domains, and contains no sender-specified routing (user@elsewhere@domain).

In simple terms: postfix will check the recipient address. If domain part wasn't defined in relay_domains (or its subdmomain), $mydestination, $inet_interfaces, $proxy_interfaces, $virtual_alias_domains, or $virtual_mailbox_domains, then postfix will reject it.

In your logs above, the recipient was someone@yahoo.com, so it is obvious why postfix rejecting it.

  • I honestly thought you nailed. I ran into a similar issue some time ago. I make the change, I tried setting mynetworks to 0.0.0.0 and I even copied a config that address the exact issue you brought to light. Same error :( bpaste.net/show/a26076c941b4 bpaste.net/show/6def40226cea – mine Feb 14 '15 at 1:15
  • Don't set mynetworks to 0.0.0.0/0. Your server will turn into openrelay – masegaloeh Feb 14 '15 at 1:44
  • Still, I really don't know what are you trying to do... Your statement about 'test basic email capabilities' was still vague. This answer only explain why you get the error. No solution given here yet... – masegaloeh Feb 14 '15 at 1:53
  • it's a standard mailserver on a public IP. All clients are dynamic and routable. I just need to find the 'send all' button (not the open relay). i.e. sasl auth. It's hitting the database fine. – mine Feb 14 '15 at 5:09
  • 1
    Good. Now, we need to verify that SASL auth was properly configured on both server and client. Could you verified it by following [this docs](www.postfix.org/SASL_README.html#server_test)? – masegaloeh Feb 14 '15 at 6:44

I'm using THUNDERBIRD as MUA and I have same issues. I solved adding the IP address of my home PC on mynetworks parameter on main.cf

mynetworks = 127.0.0.0/8 [::ffff:127.0.0.0]/104 [::1]/128 MyIpAddress

P.S. I don't have a static ip for my home PC so when my ISP change it I ave to adjust every time.

0

FWIW adding the below worked for me. I am using an spf checker which is the need for the check_policy_service. My client is squirrelmail and my server postfix.

smtpd_recipient_restrictions = permit_mynetworks, permit_sasl_authenticated, check_policy_service unix:private/policyd-spf
