login to smtp.mail.yahoo.com failed
I have created a Yahoo mail account and configured it in Thunderbird correctly according to the Yahoo (https://help.yahoo.com/kb/SLN3773.html) and Mozilla (http://kb.mozillazine.org/Yahoo) docs.
I can access IMAP without any problem but SMTP always fails. I've checked the config repeatedly, deleted and re-added the password in Thunderbird, changed the Yahoo password and reconfigured Thunderbird yet again, disabled and re-enabled Yahoo's 'insecure' mail access option, all without any success. Every time I try to send an email via Yahoo on port 465 I get the same error 'login to smtp.mail.yahoo.com failed'. If I try with port 587 it just times out. I tried OAuth2 authentication but that failed as well.
I have no idea how to proceed from here.

I eventually stumbled on the solution myself: password length.
I was using a 36-random-character password (generated by KeePassX) for my Yahoo mail. That worked ok for web login and IMAP, but it was too long for Yahoo's SMTP server. No idea why, it doesn't make sense to me why it would work for some protocols but not others.
Anyway, when I changed my Yahoo account to a 24-random-character password SMTP started working.
I have since found a forum post stating that the maximum length for Yahoo passwords is 32 characters, but I found no supporting info in any official Yahoo docs. Also, my 36 character password was working with web login and IMAP, so maybe it's a sign of inconsistency on the part of people at Yahoo.
