Thunderbird Autoconfig is specified on this page: Thunderbird:Autoconfiguration:ConfigFileFormat

We have an entry to says that the IMAP login = email local part (and not the full email address):

    <incomingServer type="imap">
      <hostname>imap.saint-ex.deuxfleurs.org</hostname>
      <port>993</port>
      <socketType>SSL</socketType>
      <authentication>plain</authentication>
      <username>%EMAILLOCALPART%</username>
    </incomingServer>

But it seems ignored by FairEmail despite advertising support for this file.

Requests:

nginx-1  | x.y.z.a - - [13/Feb/2024:11:31:33 +0000] "GET /.well-known/autoconfig/mail/config-v1.1.xml?emailaddress=nicolas@saint-ex.deuxfleurs.org HTTP/1.1" 200 1020 "-" "Mozilla/5.0 (Linux; Android 10; Nokia 7.1 Build/QKQ1.190828.002; wv) AppleWebKit/537.36 (KHTML, like Gecko) Version/4.0 Chrome/91.0.4472.101 Mobile Safari/537.36"
nginx-1  | x.y.z.a - - [13/Feb/2024:11:31:33 +0000] "GET /autodiscover/autodiscover.xml HTTP/1.1" 404 19 "-" "Mozilla/5.0 (Linux; Android 10; Nokia 7.1 Build/QKQ1.190828.002; wv) AppleWebKit/537.36 (KHTML, like Gecko) Version/4.0 Chrome/91.0.4472.101 Mobile Safari/537.36"

Hypothesis:

  • We don't send the correct mime type currently, it might be the issue (we send Content-Type: text/plain and should send Content-Type: text/xml instead).
  • %EMAILLOCALPART% might not be supported (should check the source code)

Possible fixes:

  • Send the correct MIME type
  • Use the ?emailaddress= query parameter to fill the field
  • Implement Microsoft autodiscover.xml

See attached screenshot of FairEmail autoconfiguration.

The 50 at the end of the smtp and imap addresses remind me of the DNS based auto discovery, where each possibility can have a priority value. Maybe this could be related?

EDIT: it does not seems so, the numbers do not match:

$ dig +short SRV _submissions._tcp.saint-ex.deuxfleurs.org
10 10 465 smtp.saint-ex.deuxfleurs.org.
$ dig +short SRV _imaps._tcp.saint-ex.deuxfleurs.org
10 10 993 imap.saint-ex.deuxfleurs.org.

  • FairEmail sends a non-empty authorization field, fixed in Aerogramme
  • FairEmail might require a Content-Type: text/xml in order to accept the autodiscovery file, fixed
