Help of SPF Implementations on exim
|
|
Hello
I am new to SPF and i install exim with SPF supports.
After the install i add the following line in the rcpt acl of my exim configuration
file
deny message = $sender_host_address is not allowed to send mail from
$sender_address_domain
log_message = SPF check failded
spf = fail
This configuration can permit to test a fail forgery attemps from domains wich publish
SPF records.(example aol.com)
A furgery aol mail from host 41.207.177.17 to my server give this error
"SPF result is unknown (permanent error) (7)"
**** SMTP testing session as if from host 41.207.177.17
**** but without any ident (RFC 1413) callback.
**** This is not for real!
