Trying to use zend mail smtp to send email from my php app login authenticated and give me this constant error I don't have to deal with I look into de 36 question here on serverfault.com changing parameters as they explain without success.

The data:

  • MY POSTFIX version 2.6.6
  • I'm on Centos 6.5
  • I'm trying to use Postfix and Dovecot with Dovecot-sasl
  • My users are virtual created
  • I'm able to sent mail via telnet on port 25 and 587
  • 5000 is my POSTFIX user
  • Ips where i'm testing my app (if it help) is listed on bl.spamcannibal.org b.barracudacentral.org pbl.spamhaus.org and zend.spamhaus.org
  • My ip server is not listed

Telnet to 587 look like this:

Trying ::1...
telnet: connect to address ::1: Connection refused
Connected to localhost.
Escape character is '^]'.
220 mail.mydomain.com ESMTP Postfix
ehlo localhost
250-SIZE 10485760
250 DSN

Testing my ssl with:

openssl s_client -starttls smtp -crlf -connect mail.mydomain.com:25

Give me this answer ,last lines (I assume is OK)

Verify return code: 18 (self signed certificate)
250 DSN

if you need anything more just ask for that.

I Need to know, if you know, where this error used to came from ,at least.

Any suggestion would be good help.

    THe error came from smtpd_recipient_restrictions on submission service in master.cf. You only permit a client who authenticated via SASL. Did you set that properly?

  • Also, you should only need to use permit_sasl_authenticated once in the smtpd_XXX_restrictions as it won't be setting up multiple sasl connections for each test, and if any of the steps rejects it, it will end up rejected in totality.

  • @masegaloeh I set that according to this wiki wiki2.dovecot.org/HowTo/PostfixAndDovecotSASL except for "permit" at the end of smtpd_client_restrictions in submission just was something I change for testing pourposes, if I replace that permit with as a reject as in the Wiki page now It gives me a "the Client host rejected: Access denied".

    @NickW you mean in the main.cf and master.cf ? Could you be more specific?

    It's not wrong the way you're doing it, it just makes things harder to read, and to understand where the connection is stopped. BTW, masegaloeh is right, permit sasl authenticated means they are authenticating via SASL, not just making an SSL/TLS connection.

In this line:

-o smtpd_recipient_restrictions=reject_non_fqdn_recipient,reject_unknown_recipient_domain,permit_sasl_authenticated,reject

You are rejecting not authenticated messages from submission port. You need change the test, to authenticate (AUTH command) or replace reject to reject_unauth_destination

  • Sorry for not come here before , was busy . This is actually what I do and everything looks fine since then. Thanks anyway and I'm going to accept this answer because is what I already have done.

    Even after this long of a period, this answer still holds true (because there are too many bad blogs out there, such as ait.com/tech-corner/… ) Dec 30 '19 at 22:55
  • I was searching to solve this problem for more than two days.. no chance.. not finding why mails was not being delivered to mailboxes! Thanks to telnet and your flawless answer to its describing error message! Jan 8 '20 at 6:55
