Ah, those are all ".smtps" - I suspect netstat on FreeBSD means "port 465" there.
If those are hung waiting to complete TLS negotiation, you'd see that.
For those, use the main-config option "host_reject_connection" rather than the
connect ACL - it operates before the TLS startup for TLS-on-connect ports,
while the ACL is run after.
I'm considering changing that, even though it's an incompatible change.
Having the ACL operate before TLS startup (for TLS-on-connect) would align
with the operation for STARTTLS, and possibly cause less surprise.
Anybody want to comment?
