How to display an image in mail.ru?

Question

Django

I'm doing a newsletter. Django1,6+EmailMultiAlternatives.
In all web services (GM, YM, Rambler), the letter is displayed perfectly (pictures + text), BUT not on mail.ru.
Pictures disappear, everything is fine with the markup of the letter itself.
To insert pictures, I use this default:

<img src="http://рф_домен/static/emails/logo.png"
                          style="display:block" 
                          alt="Альт"
                          width="540" 
                          border="0" height="140" 
                          hspace="0">

When viewing the code of the letter page on the mail.ru web face, you can see that the pictures are issued from the cache ( https://proxy.imgsmail.ru)
But if you send the same HTML letter via Thunderbird that Django sends, then the pictures are all fine, and on the web face of mail.ru they are already issued from //af6.mail.ru.
What am I doing wrong?

Answer 1

Resolved, pictures located at the address in the .rf zone are crookedly cached, through punny norms.

Answer 2

The same problem, only the server is not in the .rf zone, but the link is still replaced with https://proxy.imgsmail.ru
