Problems with encoding in 6.0.3

[HidX]

Good evening.

Previously, when I worked with 6.0. (0-1-2) version of Zimbra, I sent a message through the console in Russian. Used for the "mutt".

After upgrading to 6.0.3, mail sent to the console began to come in broken encoding.

For example:

echo "Архивация успешна" | mutt -s Тестинг user@domen.ru

If you view the original message and choose UTF-8 then the letters are displayed normally.

You can do something that would be a letter in the Russian came back with a normal coding?

To update(to 6.0.3) all was well...
