No problem, can tell it once again and bit more detail.

Ok, as I understood, Claws Mail doesn't support opening .eml files from command line ?
$ claws-mail 'filename.eml' → does nothing but error message on claws.log file (debug enabled): 'filename.eml' not found.

Sylpheed for example supports this:
$ sylpheed 'filename.eml' → opens 'filename.eml' file in Sylpheed Message View. No error messages in sylpheed.log.

With .eml part or attachment if I select 'Open with' '/usr/bin/claws-mail %s', it does nothing, but error message in claws.log (debug enabled): 'filename.eml' not found. '/usr/bin/sylpheed %s' works normal, no errors in log file.

That's too cumbersome. Better to keep Claws-mail and Sylpheed both installed.
