I'm trying out the SPF code for the first time and I have a question.
But first - my ACL.
drop message = REJECTED - SPF - $sender_host_name is not allowed to
send mail for domain $sender_address_domain - $spf_smtp_comment
log_message = REJECTED - SPF - $sender_host_name is not allowed to
send mail for domain $sender_address_domain - $spf_smtp_comment
spf = fail
So - is this safe? Will I get any false positives?
Lets say that a person has an email address joe@??? and that
email forwards to an account on my server joe@???. Will there be
any errors relating to domain1.com being allowed to forward the message
to domain2.com if the SPF record is restrictive? Is SFP smart enough to
look at all the received lines and figure it out?
