Sujet: [exim] accept mail from local domains without checking rbl
I have inherited a sysadmin position and dont know a ton about exim. I
had a crash-course by the previous guy, but still need some help. It
seems email sent within our network is being checked for blacklist. How
can I prevent this from happening?

Seems to me i could just move the 2 accept domains rules above the rbl
rule. Is this correct?

Thanks
Steve

my ACL:


acl_check_rcpt:

# Accept if the source is local SMTP (i.e. not over TCP/IP). We do this by
# testing for an empty sending host field.

accept hosts = :

# Deny if the local part contains @ or % or / or | or !. These are rarely
# found in genuine local parts, but are often tried by people looking to
# circumvent relaying restrictions.

# Also deny if the local part starts with a dot. Empty components aren't
# strictly legal in RFC 2822, but Exim allows them because this is common.
# However, actually starting with a dot may cause trouble if the local
part
# is used as a file name (e.g. for a mailing list).

  deny    local_parts   = ^.*[@%!/|] : ^\\.


# Accept mail to postmaster in any local domain, regardless of the source,
# and without verifying the sender.

#  accept  local_parts   = postmaster
#          domains       = +local_domains


# Deny unless the sender address can be verified.

  require verify        = sender

  # we can skip expensive spam filtering on them.
