#* This is only for intranet deployments, we won't be shipping any configs by default anymore, in favor of the following alternatives.
# Try to get the configuration from the email provider (not yet implemented)
## Try to contact http://autoconfig.<i>emailaddressdomain</i>/mail/config-v1.xml?emailaddress=<i>emailaddress</i> , e.g. http://autoconfig.example.com/mail/config-v1.xml?emailaddress=fred@example.com and see whether that host/URL exists. The returned file must have the [[Thunderbird:Autoconfiguration:ConfigFileFormat|ConfigFileFormat]] as below. <!-- As fallback, try http://<i>emailaddressdomain</i>/.well-known/autoconfig/mail/config-v1.xml ?emailaddress=<i>emailaddress</i> . --> See [https://bugzilla.mozilla.org/show_bug.cgi?id=534722 bug 534722].
## and/or, define a DNS TXT record on domain example.net (for my.account@example.net) which contains an URL like e.g. https://www.example.net/mozilla.xml , which also returns this file format. A similar, but slightly different proposal is described in detail on [[Thunderbird:Autoconfiguration:DNSBasedLookup|DNSBasedLookup]].
## and/or use DNS SRV records _imap._tcp.example.com etc. (Problem: Doesn't provide username form etc..)
