Hi,,
I know this is very common question but i have not found any answer
We use Exim 4 as Gateway server for inbound and outbound routing.
There is some problem i have not a qlue to resovl
1- I need to allow my internal server us exim to relay outbound messages.
But Exim do not allow my server to relay..!
2- I need prevent all messages from @mydomain.com to @mydomain.com
it case. i wan to prevent any SMTP hosts to fake user1@mydomain to send
user2@???
Here is summery of my config
domainlist local_domains = @ : lsearch;/etc/exim/localdomains (contain
mydomin.com)
domainlist relay_to_domains =
hostlist relay_from_hosts = 172.31.11.5:172.31.11.3:127.0.0.1
acl_smtp_rcpt = acl_check_rcpt
begin acl
acl_check_rcpt:
accept hosts = :
deny local_parts = ^.*[@%!/|]
accept local_parts = postmaster:ravms:Mailer-Daemon
domains = +local_domains
require verify = sender/no_details
deny message = host is listed in $dnslist_domain
dnslists = sbl.spamhaus.org : \
relays.ordb.org : \
opm.blitzed.org
accept domains = +local_domains
endpass
message = unknown user
verify = recipient/defer_ok/callout=5s/callout_defer_ok
accept domains = +relay_to_domains
endpass
message = unrouteable address
verify = recipient
accept hosts = +relay_from_hosts
# verify = recipient
accept authenticated = *?deny message = relay not permitted,
not authenticated
deny senders = *@partial-dbm;/etc/exim/access.db : \
dbm;/etc/exim/access.db
deny message = unrouteable address
hosts = !127.0.0.1/8:0.0.0.0/0
!verify = recipient
