Comment on Bugzilla Postfix e-mail integration by david415

Yeah I remember seeing that permissions issue.
But I looked at the latest postfix aliases files and found I put this there :
bugzilla: “|(sudo /var/www/bugz/nobody-chown ; /var/www/bugz/email_in.pl -vvv 2>/tmp/emailin.log)”

In this context the pipe is owned by nobody.
It looks like I setup an ugly hack… nobody-chown does this:
chown nobody /var/www/bugz/data/params

Really I should be executing the email-in.pl with sudo as the bugzilla user or something.
I’ll probably have to revisit this project again when we actually want to use bugzilla e-mail…

I just spent a couple of days trying to get this to work with .forward/.procmail, and eventually discovered that when Postfix invokes the pipe in .procmail it does not give the process the supplementary groups defined in /etc/group for the ‘bugzilla’ user (see http://article.gmane.org/gmane.mail.postfix.user/88627/match=supplementary+group). Are you seeing the same problem with your approach?

I solved mine by doing “chown -R bugzilla.apache /opt/bugzilla”
