The error message from yahoo clearly indicated that some were relayed. As
I wrote before, look into your logs where the spam came from. It's hard to
help you without this information.

Which is not the case. The acl_smtp_auth controls if somebody can use the
AUTH command, not the authentication itself. Remove it, it's futile in the
way you use it (most people also don't need it). The same is true for your
acl_smtp_starttls, btw.

From what I can see, you are not an open relay.

No. What should be the purpose of doing so? It's totally useless and
unrelated to your issue.

Without further information (especially from your log files) nobody here
can tell you.

remove it from your queue directory or (better) use some combination of
"exim -Mrm" with exipick or ...

The names of the authenticators are arbitrary, you can use any name you
like. The appear in the log and can be used in conditions, though the
latter is seldom used, I'd say.
