I replied to a letter from @....
yahooMail has put my reply to the Spam folder
(X-YahooFilteredBulk: 220.127.116.11) despite correct SPF and DKIM:
> Received-SPF: pass (domain of lena.kiev.ua designates 18.104.22.168 as permitted sender)
> Authentication-Results: mta1163.mail.bf1.yahoo.com from=lena.kiev.ua; domainkeys=neutral (no sig); from=lena.kiev.ua; dkim=pass (ok)
The letter was plain text, the only URL in body was with the
same domain as in From.
Today I got feedback report:
> From: Yahoo! Mail AntiSpam Feedback <feedback()arf.mail.yahoo.com>
> This is an email abuse report for an email message received from lena.kiev.ua on Sat, 09 Feb 2013 13:37:04 PST
I asked the recipient what she did, her reply:

I.e. she has read my reply in Spam folder, then deleted it - logical, no?
It had't happened to her to click "not spam" first, then find the
letter in Inbox and delete it there. She went a logical way of least
resistance - apparently she just clicked Delete after she had read the letter.
yahoo treated that as her confirmation that my letter was spam. :-/
