853103 - Autoconfig doesn't check <domain>/.well-known/

Status: VERIFIED INVALID

(Thunderbird :: Account Manager, defect)

Description

[alex]

User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:19.0) Gecko/20100101 Firefox/19.0
Build ID: 20130307023931

Steps to reproduce:

Tries setting up autoconfig for my domain.

I have a hosting Server with a script that returns the config.xml for a given email with the user name. (Build as descriped here: https://developer.mozilla.org/en-US/docs/Thunderbird/Autoconfiguration )

There is also a mention about what URLs are checked.

First Thunderbird should check http://autoconfig.<domain>/mail/config-v1.1.xml and then http://<domain>/.well-known/autoconfig/mail/config-v1.1.xml




Actual results:

First one works perfekt. The second one not! I looked arround and see that if the domain has not entry for autoconfig Thunderbird does NOT make any try to check .well-known..

I did a capture with wireshark to see if the http request is mad and there is no connect at all.


Expected results:

Request to http://<domain>/.well-known/autoconfig/mail/config-v1.1.xml should have been made. But wireshark shows nothing as long as there is not entry for autoconfig on the domain.

We do check it.

However, we check the second only if the first didn't work. That is intentional.

Does http://autoconfig.<domain>/mail/config-v1.1.xml work on your domain? Please tell us your concrete, actual domain, so that I can take a look.

I talked with the report per email. His DNS didn't have an entry for <domain>.

To be more specific there was no A record for the TOP Level like

example.com    A    a.b.c.d

only one for www.example.com. So to get the autoconfig to work without autoconfig entry make shoute the TOP Level of the domain points to the webserver you place the config-v1.1.xml on.
