Did you somehow turn off "sync_try_imap" (in imapd.conf on the

If it's on (by default or otherwise), sync_client will always try to
make an IMAP connection to the replica before falling back to CSYNC if
that fails. If it's off, it will only try CSYNC, which requires
sync_server to be running on the replica. It sounds like your
sync_client is only trying CSYNC, which makes me think "sync_try_imap"
is turned off.
Here's the relevant paragraph from the imapd.conf(5) man page:
sync_try_imap: 1
Whether sync_client should try to perform an IMAP
connection before fall‐
ing back to csync. If this is set to "no",
sync_client will only use
csync. Prefix with a channel name to apply only for
that channel
I did indeed see that option on the manpage, and confirmed I hadn't
inadvertently disabled it. I tried forcing it on by explicitly enabling
it in imapd.conf, but it made no difference.
