Your mail is being delivered to recipients through postini. The spf
record for the mailman.canby.k12.or.us domain is "v=spf1 mx ~all"
which says the MX for the domain, which also is
mailman.canby.k12.or.us, is authorized to send mail from this domain
and every other server is a softfail.

You could change this record to "v=spf1 mx ip4: ~all" ore
equivalently "v=spf1 mx a:na3sys009amx210.postini.com ~all" to
authorize this particular server to send mail on your behalf, but
postini probably has several servers so you probably would want
something like
"v=spf1 mx ip4: ~all" to authorize the range where 'x'
is the dumber of bits to consider and would have to be provided by
postini, or perhaps postini has other mechanisms for specifying all
their servers in SPF records.
