SPF Is Blocking Mail from Me to Me, but I've Never Heard of SPF

Jul 1, 2004, 1:43 PM

Post #1 of 5 (2253 views)

Forgive my unfamiliarity with the technical jargon of e-mail,
but i am hoping that someone here can at least point me in the
right direction to solve my problem.

SPF is suddenly blocking mail from me to myself, but I have
never heard of SPF.

Coincidentally, my cable modem was changed just this morning,
and the problem developed after that, but my cable company says
the problem is not at their end.

The bounce message appears below.

My e-mail name is housed at namezero.com. E-mail sent to me
goes to my e-mail account at nycap.rr.com, and then to
fastmail.fm. I don't know at what point SPF intercepts it. I
originate my e-mail at fastmail.fm.

Thanks much.

Hello,

Apparently your problem is that you are sending mail using an outgoing
smtp server that is not authorised by the owner/maintainer of the domain
alcannistraro.com. Doing a lookup for alcannistraro.com reveals that the
nameservers for that domain publish the spf record "v=spf1
a:smtp.mailix.net -all". This means that the only outgoing mail server
that is allowed to send mail from alcannistraro.com is smtp.mailix.net.

Are you maintaining the domain yourself? I guess not, or else you would
have put the spf record there yourself. You probably need to talk to the
person who maintains the domain alcannistraro.com, and explain that you
want to send email from fastmail.fm (if I understand your email
correctly).

Hope this helps,

Koen

Ironically, fastmail.fm is bouncing itself. That's its mail server.

In your DNS, you have to specify that the outgoing server of fastmail.fm is allowed to send mail on behalf of your domain. Use the SPF file generator at spf.pobox.com...

Settings have been discussed on various fastmail forums. Here are some
distilled recommendations.

If your domain has its mail vhosted by fastmail then a component like

mx/24

should do it. Otherwise

mx:fastmail.fm/24

should do it. The fastmail people have implied that their out-going
servers are
all "close" (well within /24) of their incoming ones.
