Good day, We switched On disclaimer by instuction. And when I add new text via IredAdminPro it appears  at /etc/postfix/disclaimer
All is fine working with english text, but with russian letters in message footer we got wrong chars like:
ЪЪЪ ЪЪЪЪЪЪЪЪFЪЪ Ъ ЪЪЪЪ ЪЪЪЪЪ ЪЪЪЪ

Could you help us, please.

Some guys on linux forums wrote about altermime
and problem in qpe.c

where string like this 
snprintf( charout, sizeof(charout), "=X", *p);

should be replaced with this one:
snprintf( charout, sizeof(charout), "=X", *((unsigned char *)p));
