Greetings,

I've recently configured SPF on my Courier mail server and have found a
few issues with it.  I'm not sure if these issues are merely par for the
course with SPF or are issues with my configuration.  So, I'm asking the
list:  Is this normal behavior for SPF?

I've set the following options in /etc/courier/bofh:
opt BOFHSPFHELO=all
opt BOFHSPFMAILFROM=pass,neutral,none,softfail,unknown
opt BOFHSPFFROM=pass,neutral,none,softfail,unknown
opt BOFHSPFHARDERROR=fail,softfail
opt BOFHSPFTRUSTME=1
opt BOFHSPFNOVERBOSE=1

Issue #1:
Very few folks seem to pass the SPF for HELO, so I've found myself using
the value 'all' for those few cases that the desired message might pass
MAILFROM or FROM, but not HELO.

Issue #2:
Not everyone has implemented SPF (most annoyingly Yahoo mail), so I had
originally set BOFHSPFMAILFROM and BOFHSPFFROM  to 'pass,none,neutral'.  I
noted that mail forwarded from other accounts was marked as 'softfail', so
I added that to the list of values.  After I noticed that my mail server
was denying specific legitimate mail messages from some of my mailing
lists, I had to put in 'unknown' because this is how the SPF marked them
and I wanted to get the messages.

Issue #3:
If I change BOFHSPFTRUSTME from 1 to 0, the local mail agent doesn't work
at all.  I can't get my local log reports.  I realize it is almost
meaningless to run SPF on one's self, but I wanted to see if my DNS
entries were being correctly interpreted.  It makes sense that 127.0.0.1
would not survive a DNS TXT lookup, so I guess I shouldn't have expected
this to work well.

So, I ask the list:  Is this normal for SPF?

Thanks for your time,

Shawn M. Jones
