Subject recoding


I have some problems with subject recoding: when someone sends
mail to RT with russian letters in “subject” field, RT displays it as
"=?koi8-r?B?wi3aIDI1NQ==?=" for example. As far as I know
such subject encoding is allowed in RFC. Can You please insert
some decoder into RT mail gate?

PS: This is Request Tracker version 1.0.2.
