[ProgSoc] Mangle From addresses - [geoff|ccf]@nospam.rift.cybersorceress.com.au

["Tony Young" <tony@nospam.rift.cybersorceress.com.au>]

Something wierd I've noticed lately is that some emails on the progsoc list
are coming 'From' geoff@nospam.rift.cybersorceress.com.au and
ccf@nospam.rift.cybersorceress.com.au.

So what? you ask

Well, rift.cybersorceress.com.au is my home machine, on a private domain, and
I know for a fact that the geoff and ccf accounts do not exist.

I also don't expect that these two people have hacked into my machine and are
spoofing emails to the progsoc list - I've had no indications of someone
successfully hacking into my machine, and I seem to remember at least Geoff
having mailed the list previously using a 'real' address.

I'm just wondering if anyone can explain what may be happening - I suspect my
mail server/procmail system is modifying the headers for some strange reason.
rift.cybersorceress.com.au is running Mandrake 7.2, Kernel 2.4.1, sendmail
8.11.0, procmail 3.14 and imap 4.7c2
