SPF policy linking to Postfix
Hello Linode Community:
I'm using my linode server with postfix for outgoing mail only.
Since i was having my outgoing emails marked as SPAM i went to the article Configure SPF and DKIM With Postfix
Here i read the section Add the SPF policy agent to Postfix
This would i believe only apply if one uses Postfix for incoming email.
Can anyone confirm the same ?
Thanks in advance.
There is no software configuration for "outgoing SPF".
It's just a DNS record that tells others that the IP address(es) of your outgoing SMTP server - is/are "authorized" to send mail.
Once you add that, it will be read and checked by the mail servers of your recipients.
Also I recommend reading the section on verification
… which explains how to check that your newly added "outgoing SPF" is indeed working.
PS - DKIM helps too and is only a little bit harder to set up.
