you have to encode your mail, as SMTP is really meant to deal with 7bit chars. I think that you can just add a "Content-encoding: 8 bit" header, but wouldn't bet money on it. Another way, that would almost certainly work, is to encode your mail QP. See Mime::QuotedPrint.

You have to encode the mail in a proper character set and include the appropriate Content-Type header as in Content-Type: text/plain; charset=iso-8859-1 if your message is encoded in ISO-8859-1.

One of the many MIME or other modules would be a good way to get your message properly encoded in the first place. The already suggested MIME::QuotedPrint is not a bad idea - the messages remain mostly human readable that way.

Makeshifts last the longest.

I've tried both methods: charset doesn't change the result at all (i get the same mistakes) while using QuotedPrint i receive the message encoded( like this:'=88=DD=88=AE=88=A8=88=BE=88=BC')

This might mean that the recipient's mail reader (MUA) doesn't handle QuotedPrintable correctly, or that you aren't sending the correct headers for it to recognize it.

Sending in 8bit is not recommended, since you might have different encodings on the sender side and the recipient side.
