I've installed spamassassin on a raq4 (after upgrading perl to 5.6.1 and not breaking GUI) for a particular user (not sitewide). I've setup a .forward and .procmailrc for the user as the spamassassin install instructions specify.
When I send a test mail to the email address it bounces and I get the following:
Final-Recipient: RFC822; <email address removed>
X-Actual-Recipient: X-Unix; "|IFS=' ' && exec /usr/bin/procmail -f- || exit 75 #user"
Action: failed
Status: 5.7.1
Diagnostic-Code: X-Unix; 550 Unsafe for mailing to programs
Last-Attempt-Date: Mon, 26 Apr 2004 15:45:45 +0100
I've not managed to find anything that leads to a solution to the problem.
Any ideas welcome.
