What steps will reproduce the problem? 1. Retrieve any message with Cyrillic encoding (KOI8-R encoding) (like Проверка). 2. The message will contain not vald Body or subject.

Maybe you already have a workaround?

Thanks.

If you have a workaround, please, send me to prosto019@gmail.com. Thanks.

Not that I know. We accept patches though! :D

You probably already know this, but keep in mind that sidePOP is alpha. It's not meant for production use at all. It has some instabilities in how it works

Thanks for letting me know of the issue though! It's helpful so that when we get to it, it can be addressed!

Hi, the error with encoding only if I send the email from Mozilla Thunderbird. If I sent the message from Gmail account - it work good. Only trouble with subject. It contain =?KOI8-R?B?9MXT1A==?=, but must be "Тест". I check it with Base64 and it work Encoding.GetEncoding("KOI8-R").GetString(Convert.FromBase64String("9MXT1A==")) - returns for me valid value.

I've seen that coming from IPhones as well.
