OK, so in the end I didn't have to use imapproxy because I have
haproxy in front of multiple dovecot proxies and their connection
is unencrypted. Well, anyway...

I found the following, which might be of interest:

  BAD Error in IMAP command UID STORE: Invalid uidset (0.001 + 0.107 + 0.106 
secs).

I assume this is Dovecot's response. But I'm still desperately
looking for the command that was sent by SOGo.

I dont't know the protocol but I suspect SOGo sending something
containing UID STORE. So what I did was

  $ tcpdump -Anli lo0 | grep 'UID STORE'

but the only thing I get when selecting a message is the error
above. Maybe this already helps?

Any advise for further debugging this is very much appreciated.
