[Techtalk] spf and mail

[Maria McKinley]

Hi there,

Weird problem I don't know how to deal with. If someone in my domain 
sends a mail to someone outside the domain, that then gets 
auto-forwarded by that mail account to a mail account inside my domain, 
it gets tagged by spamassassin, primarily because of an SPF fail. The 
claim is that my domain does not have an SPF record published, but that 
is not true, and every other mail coming in my domain from my domain 
doesn't have this problem. Somehow forwarding the mail to our mail 
server bypasses this check or forges this check or checks with the 
planet mars to find out we don't have an SPF record, when really we do. 
Anyone know enough about forwarded mail to venture a guess as to how 
this is happening and/or how to fix it?

thanks,
maria
