Sync enforcement is done as part of figuring out what the incoming SMTP
verb is, long before ACLs are applied. The ACL for a given command can
not affect whether or not sync enforcement applies to _that_ command.
I suggest using a _connect_ time ACL to set `control = no_enforce_sync`
and then use the _HELO_ time ACL to re-apply `control = enforce_sync`
if _not_ Thunderbird.
