[gentoo-user] SPF & sendmail: howto?

[Jarry]

Hi,

I would like to integrate Sender Policy Framework (SPF) with my
MTA (sendmail), but can not find any documentation for dealing
with SPF, Sendmail & Gentoo.

I could install mail-filter/libspf2, but how can I make sendmail
use it? There are milters for SenderID, DKIM, or DK in portage
tree, but nothing for SPF...

I assume you have a perfectly legitimate reason for still using sendmail in 
this day and age?

My advice is to migrate to postfix (best all-round MTA out there unless you 
have special needs) and google again for the HOWTO. You will be pleasantly 
surprised by the many many hits that come back.

To enable SPF on outgoing mail all you have to do is create a SPF record
and put it in your /var/bind/domain.tld.hosts file, assuming your using
Bind.

That's all I did and when I send email to Google its says...

Received-SPF: pass (google.com: domain of jason@jasoncarson.ca designates
69.196.152.151 as permitted sender) client-ip=69.196.152.151;

I use Postfix and recommend you switch. If you want to filter incoming
mail with SPF then you have to configure some stuff in the
/etc/postfix/main.cf and /etc/postfix/master.cf files. Google it for the
way to do it.

There are a number of SPF milters that can be used, but (AFAIK) none of
them are in the portage tree. The one I use is sm-spf
(http://smfs.sourceforge.net/smf-spf.html).

For ~10 years I've been a satisfied sendmail-user. Does it count for a
legitimate reason?

I have it. But that is for other MTA's receiving mails from my one.
I want to use SPF for incomming mails too...

Thanks, but I'd prefer to stick with sendmail till the end of its days.
Or at least till the first usable sendmailX/MeTA1, whatever comes first...

Finally someone who does not suggest me to switch to other MTA!
btw, It is strange, there is a milter for SenderID (which iirc is in some
way
close to Microsoft) in portage tree, but nothing for openSPF. I will try to
make an ebuild. Maybe there are still more "real unix admins" using
old'n'good sendmail. But no flame over "which MTA is better", please.
(anyway, we all know Sendmail is the best! :-)

Yes it does.

Most extant sendmail users in my experience have it because "it came with the 
CD". Or they have a pointy haired boss who doesn't actually USE it, but 
insists that the staff do.

Such folk are much better off with an alternate. I just needed to know which 
camp you were in.
