--- Comment #2 from Matthew Frost <matthewf-eximbugzilla@shop.frost.net> ---
I agree it doesn't show up under -bh.

log.c line 967 seems to be the source of the check:

/* If no log file is specified, we are in a mess. */

if (!(flags & (LOG_MAIN|LOG_PANIC|LOG_REJECT)))
log_write(0, LOG_MAIN|LOG_PANIC_DIE, "log_write called with no log "
"flags set");

Can you get a debug run of your daemon showing the issue?

The:

"dropped by 'connect' ACLNULL"

message appears to originate in smtp_in.c via log_connect_tls_drop

/* Run the connect ACL if it exists */

user_msg = NULL;
if (acl_smtp_connect)
{
int rc;
if ((rc = acl_check(ACL_WHERE_CONNECT, NULL, acl_smtp_connect, &user_msg,
&log_msg)) != OK)
{
#ifndef DISABLE_TLS
if (tls_in.on_connect)
log_connect_tls_drop(US"'connect' ACL", log_msg);
else
#endif
(void) smtp_handle_acl_fail(ACL_WHERE_CONNECT, rc, user_msg, log_msg);
return FALSE;
}
}

Bingo. Both smtps and a connection_reject log_selector are needed.

A bit of an odd combination, the log_selector and clearing log_reject_target -
but fixable. eb09d0da1fb9 addresses.
