Not really. MIME is a structured format and as such it may result in a
bunch of encrypted, non-nencrypted, signed, unsigned,
message/alternative sub-documents. Thus it is not easy to write a
general purpose command line tool.
You may start with gpgparsemail which is not installed bald build as
part of gnupg in the tools directory. It returns an annotated format
which might be easier for further processing steps than plain MIME.
If you only want to decrypt a standard MIME encrypted mail, it is easy.
Simply pipe the entire mail through gpg and you will get the decrypted
MIME container. Then use mimencode or similar tools.
Die Gedanken sind frei. Ausnahmen regelt ein Bundesgesetz.
