sure, but what happens after STARTTLS is the same, AFAIK.

143 is imap. If you ment smtp (25): This was already possible with TB
1.0x. I used smtps to save a little time on high-latency connections.

The authenticator is called long before the DATA phase, so this cannot be
the problem. Same applies to TLS.
I cannot think of single way where these things will change what happens
in an ACL, as long as you don't check for them or there's a bug in Exim.
You can try this yourself: Disable the DATA and MIME ACLs and check again.

I didn't see any debug output.

Even better, but where's the output? It produces several pages.
