Here is the Acl - it is bog standard except for hosts allow.

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 = 127.0.0.1 : 193.63.51.46

# 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



############################################################################
#
  # There are no checks on DNS "black" lists because the domains that
contain
  # these lists are changing all the time. However, here are two examples of
  # how you could get Exim to perform a DNS black list lookup at this point.
  # The first one denies, while the second just warns.
  #
  # deny    message       = rejected because $sender_host_address is in a
black
list at $dnslist_domain\n$dnslist_text
  #         dnslists      = black.list.example
  #
  # warn    message       = X-Warning: $sender_host_address is in a black
list a
t $dnslist_domain
  #         log_message   = found in $dnslist_domain
  #         dnslists      = black.list.example


############################################################################
#

# Accept if the address is in a local domain, but only if the recipient
can
# be verified. Otherwise deny. The "endpass" line is the border between
# passing on to the next ACL statement (if tests above it fail) or denying
# access (if tests below it fail).

  accept  domains       = +local_domains
          endpass
          message       = unknown user
          verify        = recipient


# Accept if the address is in a domain for which we are relaying, but
again,
# only if the recipient can be verified.

  accept  domains       = +relay_to_domains
          endpass
          message       = unrouteable address
          verify        = recipient


# If control reaches this point, the domain is neither in +local_domains
# nor in +relay_to_domains.

# Accept if the message comes from one of the hosts for which we are an
# outgoing relay. Recipient verification is omitted here, because in many
# cases the clients are dumb MUAs that don't cope well with SMTP error
# responses. If you are actually relaying out from MTAs, you should
probably
# add recipient verification here.

  accept  hosts         = +relay_from_hosts


# Accept if the message arrived over an authenticated connection, from
# any host. Again, these messages are usually from MUAs, so recipient
# verification is omitted.

accept authenticated = *

# Reaching the end of the ACL causes a "deny", but we might as well give
# an explicit message.

  deny    message       = relay not permitted

Maybe you should show your complete ACL? Sorry, but I don't have access
to your server, so I can't check it myself ;)

Looks better now. I prefer Mozilla and pine myself.
