Server Fault is a question and answer site for system and network administrators. It's 100% free, no registration required.

All emails sent from the server are displaying Cyrillic letters as weird characters, for example: Можно.

Regular alphabet letters are properly rendered.

I searched all across the web but was not able to find any solutions.

Here is some information about the system:

  • Dedicated server with Windows 2008 and IIS7
  • Application are in PHP (run as FastCGI)
  • If of any importance, Smartermail is installed on the server

The emails are sent using PHPs mail() function through a Drupal website. Encoding on that site is set up properly and there are no display issues on front end.

Where is the problem? How can I make Cyrillic letters to be properly encoded?
Any help is greatly appreciated.



Here are the email headers:

Ivan, you need to provide more information about your setup, configuration and environment for us to even understand what problem you are having. – Brent Pabst Nov 16 '12 at 17:33
Thanks for your comment Brent :) I updated my post. Let me know if I should post some other information as well. – Ivanhoe123 Nov 16 '12 at 21:23
No, a little more is needed, what is sending the messages, how are they actually being sent, etc. – Brent Pabst Nov 16 '12 at 21:35
Thanks again - I added more info to the answer. – Ivanhoe123 Nov 16 '12 at 21:43
Add that broken message headers to the question, it is impossible to guess correctly otherwise. – Andrey Voitenkov Nov 16 '12 at 21:57
