Pkg exim4 users - Jun 2008 - unconditional accept in ACL

Hello,

I''ve got my first exim installation up and running, thanks to Marc and
great Exim documentation.

There is one thing in 30_exim4-config_check_rcpt which I''m not very
sure
of - the final ''accept'':

<quote>
# At this point, the address has passed all the checks that have been
# configured, so we accept it unconditionally.
</quote>

What is rationale behind this approach? In access control lists I''m
used
to default ''deny'' and then enabling only if policy criteria
are met.

Unconditional ''accept'' at the end of ACL chain makes me a bit
uneasy,
thought it probably has its good reason.

Thanks for your comments.

It''s the way upstream does things, and I don''t want to divert
too far
from them when their configuration works. ACLs are a rather new thing
in Exim, and I guess that Philip wanted Exim 4 to work as similiar as
possible to Exim 3.

Historical ones, I guess.

Please don''t clutter my personal mailbox with support requests that
should be on the mailing list.
