I was always able to send books by email to my Kindle account, but that stopped working this morning. I get the below error. I can send the book as an attachment from my gmail account without problem. Do I need to set up SMTP and if so is it safe to enter my gmail password in calibre?
Sending failed...
Traceback (most recent call last):

OSError: Failed to send mail: SMTPRecipientsRefused({'my
account@kindle.com': (550, b'5.7.1 IP address blacklisted by recipient')})
On a side note, since the Kindle switch to EPUB, all my books are sent without cover, even if I change the metadata in Calibre. Is there a way to fix this?
Thank you
