[Exim] exim rejecting mails from sites that were ok.

We have recently moved from exim 2.x to exim 4.12. We are getting lot

of mail reject.
Our ACL is
check_recipient:
  accept  hosts = :
  accept  recipients = postmaster@??? : \
      postmaster@???
  deny    hosts = ! /mail/exim/files/net_reject_except : \
      ! * : \
      *
  deny    hosts = ! /mail/exim/files/net_reject_except : \
      +include_unknown:partial-lsearch;/mail/exim/files/host_reject :
/mail/exi

# address is in rbl-plus.mail-abuse.ja.net - so rejected
  deny    message = host is listed in $dnslist_domain
          dnslists = rbl-plus.mail-abuse.ja.net:rbl.maps.vix.com
  deny    senders = *@partial-lsearch;/mail/exim/files/sender_reject :
lsearch;
  require verify = sender
  accept  domains = +local_domains
  accept  domains = +relay_domains
  accept  hosts = +relay_hosts
  deny    message = relay not permitted

# ACL that is used after the DATA command
check_message:
  warn    !verify = header_sender
  accept

# End of ACL section

One such E-mail address is 62.254.211.4

another one is 193.130.228.132.

Previously they could send us e-mail - but not from yesterday.

Any help would be appreciated.

Many thanks
