I can imagine, that some protocol need the mail_plugins=zlib directive too?

Hey there,
i need some help with an administrativ dovecot question.
I run a dovecot 2.2.33 ubuntu server with mdbox and „zlib_save = gz zlib_save_level = 6“. Now i want to fetch the mailheader from some mails via doveadm fetch -u <user> hdr uid <uid>. The only thing what i receive is some binary stuff. Is there a way, i can tell the dovemadm fetch command, that he should deflate the output for me?
Yours sincerely Pascal Rudolf
This should happen automatically. Can you provide doveconf -n?
