I'm currently using 1.07 (and used all realeases since at least 0.9)
with smtps (port 465, tls-on-connect), never had _any_ problem with it.
It's very unlikely that your 550 is not caused by some ACL.
If you want the real reason, run "exim -d -bd 2>&1 | less", send a
message with TB and search for "550". Depending on the problem, you
might have to modify the debug optinos, e.g. "-d+expand".
