Yahoo accounts not receiving mail

Hello, I can’t seem to send mails to yahoo accounts. I found this nodemailer github issues thread (https://github.com/nodemailer/nodemailer/issues/677) where users were having problems sending to gmail and yahoo accounts.

I also had this problem until I added the name field to my SMTP mail config. Adding the name field fixed the problem for sending to gmail accounts, but messages to yahoo accounts are still disappearing. (see my comment on the same github issues thread: https://github.com/nodemailer/nodemailer/issues/677#issuecomment-572298829)

Any advice? thank you!
