551692 - Incorrect autodetection of mail servers

Status: VERIFIED INCOMPLETE

(Thunderbird :: Account Manager, defect)

Description

[Malamut]

User-Agent:       Opera/9.80 (Windows NT 6.1; U; ru) Presto/2.5.22 Version/10.50
Build Identifier: 

Thunderbird 3.0/3.1b1 can not correctly detect simple configuration of SMTP server, when SASL authorization is allowed only after TLS session is opened. Moreover, Thunderbird detect such server as using SASL, but not using TLS. And so there is a big red warning and moreover nothing is working without manual changing setting of SMTP server after creating account. It's look very strange, because Thunderbird must start TLS to detect that server allow SASL authorization.
SMTP server configuration is very simple, for example, Postfix with smtpd_tls_auth_only = yes option. And all work perfectly with such server, except a creating account wizard.

Reproducible: Always

Steps to Reproduce:
1. Postfix with SASL authorization and TLS encryption.
2. Switch on this option in main.cf:
  smtpd_tls_auth_only = yes
3. Both IMAP and SMTP server has mail.domain.com address and working correctly.

1. What do you mean with "SASL auth"? SASL is purely a server-side API and has absolutely not concern on the client. Do you mean AUTH PLAIN or AUTH CRAM-MD5 or both?
2. I don't understand what you mean with "detect such server as using SASL, but not using TLS". Our detection of SSL and STARTTLS should be independent of authentication.
3. Please provide the hostname of an example server exhibiting the behavior.

1. AUTH PLAIN LOGIN
2. Well, as I wrote, my server has STARTLS encryption and authorization. But it has
smtpd_tls_auth_only = yes
in Postfix configuration (http://www.postfix.org/postconf.5.html#smtpd_tls_auth_only)
So Postfix doesn't annonce SMTP authorization before starting TLS session.
And Thunderbird when adding new account automatically detect such server as using plain SMTP authorization, but DOESN'T using any encryption. And then as a result nothing works, after you go to Account Settings->SMTP servers and select STARTLS in server options.
3. Unfortunatelly I can't create an example server now(((

Please try again with a latest-trunk nightly, this might be bug 556491.

From your description, it should work. We test STARTTLS mode (including detection of auth) separately from no-SSL modes.

If you think the bug still exists, please give exact, concrete and detailed reproduction steps, including what you see.

If you can't give an example server, at least tell us the responses, without and with STARTTLS. See
<https://developer.mozilla.org/en/Thunderbird/Autoconfiguration#How_to_probe_mail_servers>
<https://developer.mozilla.org/en/Thunderbird/Autoconfiguration#STARTTLS>

Also, for additional information, set advanced prefs mail.wizard.logging.* to "Debug" and give the output.
