Dear friends,
can one help me getting rid of messages like this:
(faked) sender emailaddress pretends to be local user
but is not sent by one of my (very few) mailservers
how can I check if the mail (with domain in my local_domains) is sent
by one of my mailservers ?
here is my acl:
acl_check_rcpt:
accept hosts = :
deny recipients = dfritsell@???
deny domains = !+local_domains : +relay_to_domains
!verify = sender/callout=30s
deny domains = +local_domains
!verify = recipient/callout=10s, defer_ok, no_cache
warn message = BAD_MAILHOST EBEWE Mail from not EBEWE
Mailserver i
sender_domains = !+local_domains : +relay_to_domains
condition = ${if eq
{${hmac{md5}{exim@ebewe}{$body_linecount}}}\
{$h_X-Scan-Signature:} {0}{1}}
warn message = X-Is-A-Bounce: 1
senders = :
deny local_parts = ^.*[@%!/|]
accept local_parts = postmaster
domains = +local_domains : +relay_to_domains
require verify = sender
accept domains = +local_domains
endpass
message = unknown user
verify = recipient
accept domains = +relay_to_domains
endpass
message = unrouteable address
verify = recipient
accept hosts = +relay_from_hosts
accept authenticated = *
# RBL
deny hosts = +rbl_hosts
message = host $sender_host_address is listed in
$dnslist_domain
dnslists = blackholes.mail-abuse.org :\
dialups.mail-abuse.org :\
relays.mail-abuse.org :\
dun.dnsrbl.net :\
spam.dnsrbl.net :\
relays.ordb.org
deny message = relay not permitted
