What is the Content-Transfer-Encoding of the email? Was the message
Base64 encoded, or is the PNG included as raw binary data?

My procmail is configured to feed incoming mail into deliver:

Recently I received an e-mail consisting of a PNG-file -- not an
attachment, the body of the e-mail had content-type image/png. That
message ended up in my /var/mail/mi mailbox -- because deliver would
not accept it:
421 4.3.0 deliver: Trying to unput wrong character
Trying to upload the same message using mbox2imap, I get:
mbox2imap: (alert) IMAP protocol error
mbox2imap: (alert) Protocol response: NO
mbox2imap: (alert) Diagnostic message: ['Message contains NUL
characters']
Why is deliver saying this, and what can I do to be able to receive
such mail through Cyrus the way I was able to receive them through
regular Unix mail for years? Thank you!
