I thought that this message of mine didn't go out due to a mail client
error that occurred during sending. However, I guess you got it anyway.
As soon as I sent it, I found and read the README documention, which I
had initially overlooked.
Also, I've been able to answer my other question, which you should have
already received: I figured out that the `message_body' argument to the
dofilter method is the name of the _file_ that the message body resides
in, not the message body data itself.
>From that, I wrote the following filter which does this authorization
test. I just set `order' to something greater than 1 in the spf filter,
and it all seems to work.
(Note: in `pythonfilter' and all the supplied filters, it might
be good to rename the first argument of dofilter to
"message_body_file" or perhaps "message_data_file".
What do you think of this idea for the next
courier-pythonfilter release?)
import re
import sys
import string
import courier.control
import courier.config
# Accepts all incoming messages that have been submitted via a
# successful AUTH dialog.
# Run before any other filter.
order = 1
# Record in the system log that this filter was initialized.
sys.stderr.write( 'Initialized the AUTH python filter\n' )
authpat = re.compile(r'\bAUTH:\s+LOGIN\b', re.I)
def dofilter( message_body, message_ctrl_files ):
lines = open(message_body,'r').readlines()
lines = map(string.strip, lines)
for line in lines:
match = authpat.search(line)
if match:
sys.stderr.write('Login authorization succeeded: message accepted\n')
return '200 Ok'
return ''
