Broken script cause postfix to fail receiving mail

[Sebastien Lemmens]

Using the following Ubuntu version:
Description: Ubuntu 14.04.1 LTS
Release: 14.04

After installing and configuring the package postfix-policyd-spf-python_1.2-1_all.deb, I get this error in mail.log that cause postfix to reject the mail with an error:

policyd-spf[1398]: Traceback (most recent call last):
policyd-spf[1398]: File "/usr/bin/policyd-spf", line 662, in <module>

On line 398 of /usr/bin/policyd-spf
string.split(sender, '@', 1)
should be
sender.split('@', 1)

Package from trusty-backports contains version 1.3 of policyd-spf that has the fix and work correctly but as backports packages are not enabled nor installed by default, I think this should be corrected.

I was wrong. The problem is not fixed in the backports package. It's still present on line 407 of version 1.3.
It only happens when a mail is received without the sender identifying itself with the HELO command, which is not normal in the first place but policyd-spf should be corrected anyway I guess.

Problem was fixed there http://bazaar.launchpad.net/~kitterman/pypolicyd-spf/1.3/revision/194 apparently released under version 1.3.2.
Ubuntu trusty-backports packaged version is 1.3.1

I uploaded an updated backport. I agree that this should be SRU'ed for the release pocket for the reasons you give, but I'm not really involved in Ubuntu development any more, so hopefully someone else will pick that up.
