Outbound Relay and SPF

I just set up SPF, and this may be a FAQ, but I searched the archive,
and didn't find any info about this issue, so here goes:

I run my own mail server (sendmail), and have set up SPF for it:

reedtz.com. IN TXT "v=spf1 ip4:66.53.195.131 -all"

All MUAs/webmail on my network connect to smtp.reedtz.com
(66.53.195.131) and all mail goes out that way.

However, when using spfmilter, I get a 'fail' status when I send myself
a test message. The problem appears to be that spfmilter sees the
Received: line containing my SMTP connection from my MUA (66.53.195.135)
to my outbound relay (66.53.195.131) as the 'client IP' (or originating
host).

What should I do? I'd really rather not have to maintain SPF records for
all MUAs. Or is this simply how it works?

I could of course put my entire /28 in the SPF record, but I'd really
like to find out how to designate my outbound server as the only allowed
server, without getting rejected.

Any help is appreciated.

Thanks,
Per
