Hi all,
I am in the process of setting up mail for a new domain and I'm interested
in people's opinions on these two:
http://en.wikipedia.org/wiki/Sender_policy_framework
http://en.wikipedia.org/wiki/DomainKeys
I have already added an SPF text DNS record for the domain as well as
installed and set up the postfix-policyd-spf-python package (I'm using
Postfix for the MTA).
During testing I realised that SPF or at least this implementation I
am using has a serious flaw that will result in mail that should be
blocked by SPF actually getting through.
I then looked at Domain Keys the wikipedia entry has a large section
titled "Weaknesses".
Has anyone else implemented these? Are they worthwhile? Problems?
Cheers,
Erik
