dovecot - Apr 2019 - No CRLF in Pigeonhole's header?

Hello,

I have been told on Freenode's #dovecot to ask here. I have Exim 4.92
complaining about "Non-CRLF-terminated header, under CHUNKING: message
abandoned" with redirects made by Pigeonhole 0.5.5 (with Dovecot
2.3.5.1). Please find relevant part of the traffic below, and help me
determine whether Exim is correct on this.

With Dovecot 2.2.36 + Pigeonhole 0.4.24.1 and required minimum of
version-related configuration changes - redirection works properly.
