SASL authentication failed... no mechanism available???? Help.

postconf -n says that outbound.mailhop.org is there and I have checked the referenced password file and the username and password are there and are correct.

I have "login" and "plain" checked under SMTP authentication in server admin.

I have SMTP SSL set to "use" and I have a valid certificate.

I have read all the mailhop outbound instructions at dyndns.com and and everything is set up correctly. I am lost. Any other ideas. When I get home I am going to take screen shots of everything, maybe you will spot something I haven't.

Thanks.

Any thoughts?

<Edited by Moderator>

*Ok, here is what dyndns.com says to do to get this service working...*

Postfix

+These instructions have been tried out and verified to work by our support staff, using Mac OS X 10.3 running postfix 2.0.10. It is expected that other versions of postfix running on various flavors of UNIX/Linux should be similarly configured.+

+These instructions assume the postfix config files live in /etc/postfix.+

+In /etc/postfix/main.cf add the lines:+

+relayhost = outbound.mailhop.org:2525+
smtpsasl_authenable=yes
smtpsasl_password_maps=hash:/etc/postfix/saslpasswd
smtpsasl_securityoptions=
+Optionally, also add the lines:+

+smtp usetls = yes+
+smtp tlsCAfile = /etc/postfix/cert.pem+
+smtp tls_session_cachedatabase = btree:/var/run/smtp tls_sessioncache+
+to enable SSL/TLS when sending outgoing mail. Note that the path info in the second command may be different depending on your system and where you have installed your certificates. The last line may be omitted, but should help reduce CPU cycles verifying the certificate chain when sending outgoing E-mail.+

+Create a file /etc/postfix/sasl_passwd with the contents:+

+outbound. ******.**:2525 userid:password+
+where userid and password are your DynDNS username and password.+

+Next, change the ownership and permissions on the sasl_passwd file to protect it from unauthorized access.+

+chown root:root /etc/postfix/sasl_passwd && chmod 600+
/etc/postfix/sasl_passwd
+Finally, create a database file from the contents of the sasl_passwd file:+

+postmap hash:/etc/postfix/sasl_passwd+
+OPTIONAL: If you wish to relay only specific domains via Mailhop Outbound, You will need to do the following:+

+Remove the relayhost = outbound. ******.** entry in main.cf, if one exists.+

+Add the following line to your main.cf file: transport_maps = hash:/etc/postfix/transport+

+Edit /etc/postfix/transport and update it with something similar to the following:+

+# Syntax: .domain transport:relay_host+
+# Specifies specific domains for local delivery+
+my.domain.com :+
+ +
+# Specify all subdomains for local delivery+
+.my.domain :+

+# Specify domains that need to be relayed through outbound.mailhop.org+
+aol.com relay:outbound. ******.**+
+hotmail.com relay:outbound. ******.**+
+Create a database file from the contents of the transport file: postmap hash:/etc/postfix/transport+
+Lastly, reload postfix: postfix reload+
+Note: Patrick Koetter has put together a very nice guide to Postfix in general and has more detailed instructions on setting up a smart host relay with SMTP Authentication.+
+If you want to change the port that Postfix uses to send outgoing mail, we have been told that you may need to change the definition of the SMTP port in /etc/services. We do not have comprehensive instructions for making this change, but some reasonable searching should get you the information you need - when changing /etc/services, though, you should be very careful, as this file controls a large part of the UNIX system's TCP/IP interactions.+

*After going back and doing exactly what they say to do I am now getting the following error in the SMTP log (mail.log)...*

??? This is driving me crazy...

<Edited by Moderator>

I am trying to send mail using the "sendmail" function in PHP on my local website. This is what is throwing the error. I will try to use mail.app and see what happens.

The issue was I needed to add a host record for mailserver.atlmetal.com in DNS to point to my mail server. Once I did that, everything works! The only problem I am having now is that when I send email using the sendmail function in PHP the email sends, but then it looks like it is sent back to me but goes to the _www account which doesn't exist so i dont know what is going on with that. When I send email using mail.app it works perfectly. Here is the mail.log in case you have any ideas for me as to how I can get the sendmail function working...
