SASL not working ""Virtual Users And Domains With Postfix, Courier, MySQL And Squirr"

[Mark_NL]

i noticed that

127.0.0.1:10025 inet n - - - - smtpd
-o smtpd_restriction_classes=
-o smtpd_client_restrictions=
-o smtpd_helo_restrictions=
-o smtpd_sender_restrictions=
-o smtpd_recipient_restrictions=permit_mynetworks,rej ect
-o smtpd_bind_address=127.0.0.1

"re ject" @ smtpd_recipient_restriction=... ???

and i've compared my working configs with yours and also noticed that i haven't set this variable: smtpd_sasl_path = /etc/postfix/sasl


edit:
/etc/pam.d/smtp contains

auth    required   pam_mysql.so user=mail_admin passwd=mail_admin_password host=127.0.0.1 db=mail table=users usercolumn=email passwdcolumn=password crypt=1
account sufficient pam_mysql.so user=mail_admin passwd=mail_admin_password host=127.0.0.1 db=mail table=users usercolumn=email passwdcolumn=password crypt=1

?? check if you didn't mistakenly created a "smtpd" instead of "smtp" file

/etc/courier/authdeamonrc
authmodulelist="authmysql"

and double check authmysqlrc

I have added that path parameter just to try if it helps, it's not working either ... and for re ject it must be copy/paste error, I have looked at main.cf now ant there is no space there ...

[Mark_NL]

Well i'm kinda out of idea's .. and it's hard to go all options one by one ..
i could have a look at your system, if you want, you can privmsg me with login data so i can have a look at your settings.

Dear Mark ,

first of all thank you for all help! I don't know how and what I did ( I really don't know! ) but sasl seems to be working now in PLAIN and LOGIN when I set in thunderbird username for SMTP server, but when I check the "Use secure authentication" I got this from thunderbird:

Sending of message failed.
An error occurred sending mail: Unable to authenticate to SMTP server 127.0.0.1. The server does not support any compatible secure authentication mechanism but you have chosen secure authentication. Try switching off secure authentication or contact your service provider.

Do you know what "Use secure authentication" means?
And is it secure enough to use STARTTLS and sasl PLAIN ?

looks like TLS is working just fine, i think your client settings aren't correct.
at least, i could make a TLS connection to your MTA .. i just didn't knew any mail accounts to send an email to
