The problem here is the sending mail user agent.
It does not generate mail headers according to RFC 2882 and RFC 2047.

According to RFC 2822 message header lines must contain only
ASCII characters (sect. 2.2).
If a message header line has to transport any non ASCII characters
they MUST be encoded as defined in RFC 2047.

You should send the authors of the senders MUA a friendly mail
pointing out that their piece of crap they call mail client is broken
and it would be a smaller PITA if they would implement a mail standard
that is around for now 10 years.

You can set

munge8bit: 0
reject8bit: 0

in imapd.conf
