Hi guys I have some problem with the SMTP server. I have followed the CentOs tutorial on this site. The problem is send the email to an external domain. I have already read the last post but I have not found any solution. Code: helo mail.mydomain.com mail from:<[email protected]> rcpt to:<[email protected]> data subject: This is a test mail to: [email protected] This is the text of my test mail. . Code: 220 myserver.mydomain.com ESMTP Postfix helo mail.mydomain.com mail from:<[email protected]> rcpt to:<[email protected]> data subject: This is a test mail to: [email protected] This is the text of my test mail. .250 myserver.mydomain.com 250 2.1.0 Ok [B]554 5.7.1 <[email protected]>: Relay access denied[/B] 554 5.5.1 Error: no valid recipients 221 2.7.0 Error: I can break rules, too. Goodbye.

Authentication needed ? You might have to authenticate yourself first, try: Code: EHLO mail.mydomain.com and look for something like this: If you see anything that starts with AUTH, it means you will have to supply a username and password. Try that Angel
You MUST first supply a user name and a password. Your post confirms what I said, you are being required to authenticate yourself. Most likely the server is set to use AUTH LOGIN if so type in right after EHLO: Code: AUTH LOGIN then you should get: Code: VXN1cm5hbWU6 which stands for username, then you should supply your email address encoded in base64. Then you will be required for your password encode it and send it as well. Good luck.
Code: 220 myserver.mydomain.com ESMTP Postfix helo mail.mydomain.com 250 myserver.mydomain.com EHLO mail.mydomain.com 250-myserver.mydomain.com 250-PIPELINING 250-SIZE 10240000 250-VRFY 250-ETRN 250-STARTTLS 250-AUTH PLAIN LOGIN 250-AUTH=PLAIN LOGIN 250-ENHANCEDSTATUSCODES 250-8BITMIME 250 DSN AUTH LOGIN 334 VXNlcm5hbWU6 xxxxxxxxxxxxxxxxxxxxxxxxxxxxx 334 UGFzc3dvcmQ6 xxxxxxxxxxxx 235 2.0.0 Authentication successful mail from:<[email protected]> 250 2.1.0 Ok [B]rcpt to:<[email protected]> 250 2.1.5 Ok[/B] data subject: This is a test mail to: [email protected] This is the text of my test mail. .354 End data with <CR><LF>.<CR><LF> Ok I have not understood. Now the email seems to me accepted but I don't receive nothing. what happens now? Any idea? thanks
Now in the log file I can see: Code: Feb 20 16:29:39 myserver postfix/qmgr[28529]: 8ED615300AE: to=<[email protected]>, relay=none, delay=0.65, delays=0.65/0.01/0/0, dsn=4.3.5, status=deferred ([B]delivery temporarily suspended[/B]: mail for mail.mydomain.com loops back to myself) any idea?
Hi Falko, the problem persists. Code: Feb 20 19:50:19 myserver postfix/smtp[21789]: 246A3530088: to=<[email protected]>, relay=none, delay=0.18, delays=0.18/0/0/0, dsn=4.3.5, status=deferred (mail for mail.mydomain.com loops back to myself)
What's in /etc/postfix/local-host-names and /etc/postfix/main.cf? Does this happen when you send a mail to a remote server or this server?
Hi Falko, It happens when I send the email by thunderbird to an external email address. in the /etc/postfix/local-host-names there are all the domain and subdomains, mail.mydomain.com included Code: [root@myserver ~]# postconf -n alias_database = hash:/etc/aliases alias_maps = hash:/etc/aliases broken_sasl_auth_clients = yes command_directory = /usr/sbin config_directory = /etc/postfix daemon_directory = /usr/libexec/postfix debug_peer_level = 2 home_mailbox = Maildir/ html_directory = no inet_interfaces = all mail_owner = postfix mailbox_command = mailq_path = /usr/bin/mailq.postfix manpage_directory = /usr/share/man mydestination = /etc/postfix/local-host-names myhostname = myserver.mydomain.com mynetworks = 127.0.0.0/8 newaliases_path = /usr/bin/newaliases.postfix queue_directory = /var/spool/postfix readme_directory = /usr/share/doc/postfix-2.3.3/README_FILES relayhost = mail.mydomain.com sample_directory = /usr/share/doc/postfix-2.3.3/samples sendmail_path = /usr/sbin/sendmail.postfix setgid_group = postdrop smtp_sasl_auth_enable = yes smtp_sasl_password_maps = hash:/etc/postfix/sasl_passwd smtp_sasl_security_options = smtp_tls_note_starttls_offer = yes smtp_use_tls = yes smtpd_recipient_restrictions = permit_sasl_authenticated,permit_mynetworks,reject_unauth_destination smtpd_sasl_auth_enable = yes smtpd_sasl_authenticated_header = yes smtpd_sasl_local_domain = smtpd_sasl_security_options = noanonymous smtpd_tls_CAfile = /etc/postfix/ssl/cacert.pem smtpd_tls_auth_only = no smtpd_tls_cert_file = /etc/postfix/ssl/smtpd.crt smtpd_tls_key_file = /etc/postfix/ssl/smtpd.key smtpd_tls_loglevel = 1 smtpd_tls_received_header = yes smtpd_tls_session_cache_timeout = 3600s smtpd_use_tls = yes tls_random_source = dev:/dev/urandom unknown_local_recipient_reject_code = 550 This is the message on the maillog: Feb 21 21:42:00 myserver postfix/smtp[23403]: D8C66C28008: to=<[email protected]>, relay=none, delay=0.2, delays=0.19/0.01/0/0, dsn=4.3.5, status=deferred (mail for mail.mydomain.com loops back to myself) If I delete the config row: relayhost = mail.mydomain.com it works! But in the header inside the email received in the GMAIL service I can see this message: Received-SPF: neutral (google.com: xxx.xxx.xxx.xxx is neither permitted nor denied by best guess record for domain of [email protected]) client-ip= xxx.xxx.xxx.xxx; Where xxx.xxx.xxx.xxx is my IP. thanks

@vaio1 I signed up on HowToForge JUST TO THANK YOU! Thank You! I've been fighting with Postfix 4.7.1 & 5.7.1 relay errors for TOO LONG; and my problems were alleviated by killing the relayhost line; just as you noted. I can't believe how many new postfix admins fight with relay issues (the amount of blogs on this topic is immense) and NONE of them had the tip to pull relayhost altogether. But plenty show you WRONG things to include on that parameters. Again -- just THANK YOU! And thanks to the others on this thread for steering vaio1 to this point.
