Hello

Can you please provide the output of doveconf -n? The version of your lz4
library could be useful also, if it is not the distributions default. ref.

Hello Teemu,

the version of my lz4 library is the most recent lz4-1.7.5, and "dovecot 
-n" output is as follows:

Many thanks for looking into this & best regards

Can you provide full logs for the imap session? Basically you can do
grep session-id logfile.
