--------------------------------------
On IRC it was suggested to post the claws.log to pastebin. It is now
posted and at 

https://pastebin.com/zb2BSvaJ

That log shows an RSS error, which is a confirmed server outage by
AlienBob.  The real issues start at 14:12:28 when attempting to log in
to imap dot mail dot yahoo dot com.  

The first failure is with the IMAP receive auth type set to AUTOMATIC.  

The second failure, starting at 14:14:49, is with the same setting
changed to PLAIN.  In this setting I also get a claws-mail ERROR screen
that states that PLAIN and LOGIN are only supported if libetpan is
built with SASL support.  Before building claws-mail I had built
libetpan and have cyrus-SASL installed first.

The last successful login, starting at 14:19:55, is with the AUTH set to
Plain-text.
 
BTW I also have a zoho.com IMAP account configured which connects
without issue using the AUTOMATIC setting, and connected each time when
the yahoo.com connections were rejected.

Hopefully this helps one of the dev's to research if this is a
claws-mail build issue or Yahoo server non-compliance.  NOTE the
Automatic setting worked on Tuesday July 25.  I'm aware that some have
noted that Yahoo reported some intermittent login issues which as of
Wednesday are reported resolved. Perhaps their resolve patched a hole
that now requires something new, like a special Third-Party app
password key?

System is Slackware64 multilib with Claws 3.15.0 libetpan 1.8 and cyrus
-sasl-2.1.26
