Hello everyone
This is my first time setting up a Postfix server system.
On a technical level, everything works out fine - Postfix is configured well and
e-mails reach their destinations.
However, they can't make it past spam filters, partly because DKIM isn't
configured.
I've tried twice following the instructions on this page:
http://www.stevejenkins.com/blog/2011/08/installing-opendkim-rpm-via-yum-with-postfix-or-sendmail-for-rhel-centos-fedora/
... but Gmail still refuses, and OpenMailbox still marks as spam.
A reported generated by sending to test_at_allaboutspam.com tells me the
following:
"Email contains invalid DKIM/Domain Keys Signature. Published Domain Keys
policy does not specify whether to accept/reject such emails. Signing your
Outbound emails and clearly specifying a policy to accept signed emails will
minimize chances of your Email being considered as SPAM. "
The system is Fedora 20, linked to domain makeandshiftjewellery.com at
87.121.52.58, and the public key is the following:
[userhidden_sorryiamparanoid_at_makeandshiftjewellery ~]$ sudo cat
/etc/opendkim/keys/makeandshiftjewellery.com/default.txt
[sudo] password for userhidden_sorryiamparanoid:
default._domainkey IN TXT ( "v=DKIM1; k=rsa; "
"p=MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQDNrAUz2hCsm/WHE6xHuvg6myN6j20XCsHwxG3eNRyKB13obqb2QKy3X4kWJu/DR1BJT61E++jBS6j9CKoYBQzMe2h5xBlkiOY89tCu6fy6C/ZYci+X0X4i399b3jA+0fTf5vYFaQfPHHXEyZtOaTZAfLxjBr3Vw0ycFNfU69xFeQIDAQAB"
) ; ----- DKIM key default for makeandshiftjewellery.com
The company where I purchased the domain confirms it's active:
v=DKIM1; k=rsa; "
"p=MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQC3nBfZd2MAbnSlfFFQJ1r

8y/hsFzdcQVOGFcvNA98L0AENkopKnu9MblBcKjQHBHr2ugoskTLktGtAPHHue/nhVBQ
9VBKtRxOnNE+IiNvQIDAQAB
What am I missing? What is this policy that allaboutspam.com is referring to?
I don't know if this is normal, but I have two keys that are the same:
[root_at_makeandshiftjewellery ~]# diff /etc/opendkim/keys/default.txt
/etc/opendkim/keys/makeandshiftjewellery.com/default.txt
