Subject: Re: [exim] Simple if-else condition in acl_check_rcpt
Sorry I use Debian style split config:

at the moment it looks like

30-exim4-config_check_rcpt

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 = :
      control = dkim_disable_verify


# check ip of connection
#  deny
#      !hosts = +filter_relays
#      #domains = +filter_domains
#      condition = ${if match_domain {$domain}{+filter_domains}}
#      message = Your IP $sender_host_address is not allowed to send
mail for $domain
#


The complete config: see attachment
