Email sent from Rails to yahoo users not delivered

Question

I'm facing following issue:

I send emails from rails using Mailer, it goes fine to all recipients except users with xxx.yahoo.com account.

I tried sending it using SMPT of

Gmail
SendGrid

In none of the case it is delivered.

It gives me following error message

554 Message not allowed - [PH01] Email not accepted for policy reasons. Please visit https://help.yahoo.com/kb/postmaster/SLN5067.html [120]

And when I open their provided link, I see following:

You'll receive an SMTP error or failed delivery message that includes "554 Message not allowed" when the content of a message you're trying to send violates Yahoo Mail policies. Content that violates policies includes; objectionable links, malicious attachments, or bad header information.

They mentioned about content, so I tried sending simple email (note same email when sent from Mail(mac) client, goes fine)

Hello Mr. Suraj,
How are you? Not heard from you for long time.
See you soon.

So, this doesn't looks related to content, so bad header information ?

If its so then, doesn't it a Rails/Mailers issue?

I don't understand how to fix this, any one came across this?

Thank you in advance.

What kind of `emails` are you sending and are you sending `bulk` emails ? — Kedarnag Mukanahallipatna, Sep 18 '18 at 15:06
User registration emails such as verification links, password reset links. But for testing I tried even simple emails as mentioned above. #2 - No bulk emails. — Rajesh Naik, Sep 18 '18 at 15:25
