Monks,

I'm trying to write a mail filter using the excellent Mail::Audit module with sendmail 8.11.6, but when the script is run by the mailer (through a .forward file), Sys::Hostname throws errors:

   ----- The following addresses had permanent fatal errors -----
|/home/matt/devel/bin/mail_filter
    (reason: 1)
    (expanded from: <matt@infernus.net>)

   ----- Transcript of session follows -----

However, when I run ~/devel/bin/mail_filter by hand, it has no problems whatsoever, and neither does Sys::Hostname:

matt@shub-niggurath:~

shub-niggurath.infernus.net
matt@shub-niggurath:~

I thought that it might be an environment issue... but my mail_filter script is chmod 744: only I can execute it! Since it's obviously being executed by me, it should have the standard paths, and be able to find /bin/hostname... right?

I can't find any indication of this happening to other Mail::Audit users, nor any mention of similar Sys::Hostname bugs. The local documentation of sendmail's .forward files isn't especially helpful: it says what they do, but not how. Help?
