Problems with mail file

Hello,

        I've been using procmail for about a year now, and I've never
had any big problems.  I decided to install it on a new computers, a Sun
SparcStation running SunOS 4.1.3.  It compiled correctly, but for some
reason I'm always getting permission errors from elm, and I can't even
directly read my mail file, /usr/spool/mail/zephyr - for some reason
when I put the procmail commands in my .forward file like this:

"|IFS=' '&&exec /usr/local/bin/procmail -f-||exit 75 #zephyr"

my mail folder becomes owned by root when new mail is received, and I
got to read it, it's fine, but then it can't close the folder and it
saves it to BOGUS.* file in the /usr/spool/mail dir.

Any ideas?

Thanks!
