Is there a way that I can setup this test to only check incoming
messages?
I set up the DNS record and it will work fine except when one of my
dial-up users sends an outgoing message. The test does exactly what I
would like it to do. When one of my dial-up users bypasses my SMTP
server, the message could be flagged as spam at the receiving end using
an SPF test.
However, if the user is sending mail correctly, through my SMTP server,
the test flags there dial-up IP as an invalid SMTP server! I would like
to turn off this test for outgoing messages while still doing other
spam testing on outgoing messages. Is there some way to do this?
Here is an example:

Subject: [Declude.JunkMail] SPF support to be added to next beta
We will be adding support for SPF ("Sender Permitted From", at
http://spf.pobox.com ) to the next beta of Declude JunkMail. This is a
system that lets owners of domains publish information on what
mailservers
people can use to send mail from the domain. We expect that this can be
very useful in blocking spam (similar to the SPAMDOMAINS test), as well
as
helping ensure that legitimate mail gets through.
http://spf.pobox.com/dns.html covers how to add an SPF record for your
own
domain. At its simplest, if all your E-mail is coming from your
mailserver, and your mailserver is listed in your MX record, you would
add
a TXT record of "v=spf1 +mx -all" for your domain. The SPF records
always
start with "v=spf1"; the "+mx" means that any E-mail from an IP listed
in
your MX records is good, and the "-all" is a default so that any other
E-mail is bad.
The SPF system is much, much more flexible than the SPAMDOMAINS test,
and
it lets domain owners control the settings (which allows them to be much
more accurate). If widely implemented, it will make it much more
difficult
for spammers to get their spam delivered.
