Thanks. BTW, i noticed that my original mail contained subject:

Subject: =?koi8-r?b?8NLPwsEg0MXSwQ==?= 1 =?iso-8859-1?q?Pr=F4b=E1_p=E8r=E5?= 2

while in your reply the subject became:

Subject: Re: =?koi8-r?b?8NLPwsEg0MXSwQ==?= 1
  =?iso-8859-1?q?Pr=F4b=E1_p=E8r=E5?= 2

i.e. it was split into two lines (probably because of `Re: '). Because
of this, it was displayed in the article buffer as
