Description Ricardo Mones 2022-10-02 10:37:12 UTC
Hi there!

This request comes from Debian bug #1020229, quoting original submitter:
[…]
> when using the auto-configure feature of a new account creation only
> "_submission._tcp.example.net" SRV record is queried, but not
> "_submissions._tcp.example.net". If example.net domain only has the
> latter SRV record, auto-configuration of SMTP server fails with the
> message "Failed: no service record found" next to the "Auto-configure"
> button.
> 
> Section 5.1 of RFC 8314 starts with the following.
> 
> > This document updates [RFC6186] by changing the preference rules and
> > adding a new SRV service label _submissions._tcp to refer to Message
> > Submission with Implicit TLS.  
> 
> Please add support for querying the Implicit TLS SRV record in account
> auto-configuration as defined above.

Request was made for the GTK+2 version, but, IIRC, nothing has changed
regarding the autoconfiguration code in latest version.

Thanks in advance,

Is there a server we can use where we can see this in effect?

No idea, asked the reporter on the Debian BTS. Let's see what happens.
