trying to understand proper setup
|
|
Hi Folks,
I run a Linux box, mostly to support mailing lists (configured w/ Debian
Sarge, and Sympa).
In addition, I have a small number of mail accounts hosted on the
machine, 1 of which logs in and uses pine, the other two use remote
clients (Thunderbird) - authenticated via MD5 challenge -response.
I've just started to add SPF records to all the domains I support, all
of which go through one mail machine, and I've published a DNS record of
the form "v=spf1 a mx ~all" (as recommended by the wizard on
www.openspf.org).
But I seem to have a problem: For the mail server, and the pine-based
email account, everything works just fine, but mail that originates from
Thunderbird fails SPF checks - presumably because it's originating from
the IP address of the client client (dynamically assigned) rather than
from the server.
Any suggestions?
Thanks very much,
Miles Fidelmn
