Change autoconfig code to match Thunderbird's current behavior

[cketti]

The set of URLs checked by Thunderbird are slightly different from what I thought when reading the documentation.

Looks good to me
You can test this against my autoconfig server project https://github.com/wdes/mail-autodiscover-autoconfig#tested-working-apps

Can you provide a debug build so I can test this and provide feedback?

Ref: #865 (comment)

Probably:

• Fixes: Feature Request: Support Mozilla autoconfig #865
• Fixes: Automatic account setup / server settings autodiscovery #4721

This implementation probably misses SRV record lookup, that would be game changer compared to other existing email apps. Probably good for another PR

LGTM

I tried the pre-release build and it seems to not work better than before. The imap server settings are still wrong

The code isn't used by the app right now.

Okay, thanks for letting me know
Looking forward to test this when it's available
