selinux exception when calling send_mail()

We don't use procmail locally to deliver suspect messages into a "spam" folder.

We just change the recipient and invoke send_mail() on the offending message instead.

Apparently this wasn't a scenario that the Fedora folks envisioned when they wrote the spamd_t selinux policy.

I've filed a bug because we've been bumping up against this:

https://bugzilla.redhat.com/show_bug.cgi?id=698398

when we transitioned from "permissive" to "enforcing".

Just a heads up about the issue.
