Hi, I'm sorry if this turns out to be a stupid question, but I'm having
some trouble working out how to construct my spf record. Here's my setup:
I have a colo server in a datacenter, which has a single ip address. I
run several websites on this server, with multiple domains that each
host a website. Email can be sent from any of these domains, via the
local sendmail server, with 'neil' as the username and then the current
website domain as the tld for the email address. So for example one of
my sites is crazyguyonabike.com, so when I send a registration email
from that site, it is 'From' neil@crazyguyonabike.com. The reverse DNS
and mx for the ip address is spidey.nilspace.com.
I also send email through this server from my home computer, which is on
a cable or DSL connection. When I do this, sendmail always seems to
attach a "may be forged" header to my emails, and I can't seem to stop
that from happening - presumably it's because my emails are "from"
neil@nilspace.com, but my originating ip address does not resolve to
nilspace.com, but rather to the cable or DSL company. This isn't the
main issue, though.
The problem is that I find that sometimes my emails just don't get
through at all. In particular, I recently changed the registration
confirmations on crazyguyonabike.com to be 'From'
neil@crazyguyonabike.com, whereas previously they came 'From'
neil@nilspace.com. I wanted the address to match the domain the person
was registering on. However now I have had a couple of instances where
these confirmations just aren't getting through at all, and this is to
yahoo.com email accounts, which previously have been very reliable in
terms of delivery. The messages aren't in the spam folder, they just
never seem to get through at all. The weird thing is that emails from
neil@nilspace.com, sent from my home computer, do get through. So the
automated ones from the server don't get through, but ones from home do,
but they are both coming from the same email server. I'm wondering if
the spf record has something to do with it - maybe Yahoo! is seeing
something weird about an email claiming to be from crazyguyonabike.com,
but my spf doesn't mention that domain? Here's my current SPF record,
generated a while back from an online wizard:
"v=spf1 a mx ptr ip4:208.64.24.170 mx:spidey.nilspace.com +all"
Should I have more stuff in there related to my other domains, even
though they all resolve to the same IP address? How about my home
connection, do I need to have anything related to that in there?
Hope this makes sense, please let me know if you need more information...
Thanks!
Neil
