unfortunately im not authorized to publish the whole headers and content, but as
an example:

in headers:
To: ""Ing. Mark?ta Kleinov?"' <x at xxx.xx>

view in the webmail or outlook
"Ing. Mark??ta Kleinov??" <mailto:kleinova at pkvp.cz>

and it should be Ing. Mark?ta Kleinov?

The problem is with From and To headers.
