Postfix does not use "smrsh". With mailbox_command, Postfix explicitly uses the compiled-in path of the Bourne shell: (void) execl(_PATH_BSHELL, "sh", "-c", command, (char *) 0); msg_fatal("execl %s: %m", _PATH_BSHELL); It is mostly pointless to use smrsh with procmail, as procmail allows users to bypass the restrictions imposed by smrsh. This is explained in the smrsh manpage: Also, including mail filtering programs such as procmail(1) is a very bad idea. procmail(1) allows users to run arbitrary programs in their procmailrc(5). -- Viktor. P.S. Morgan Stanley is looking for a New York City based, Senior Unix system/email administrator to architect and sustain our perimeter email environment. If you are interested, please drop me a note.

Postfix will use $local_command_shell for commands chosen by users. However it will use /bin/sh for commands chosen by the administrator. Wietse

When I feed an e-mail to procmail it just works, when I change the mailbox_command back to /usr/bin/procmail I get the same problem.

Nope!!! WHen I execute procmail from the commandline it works perfectly. As soon as I put it in my .forward or in the main.cf it fails. -- Adrian P. van Bloois Postbus 2575 email: adrian(a)accu.uu.nl 3500 GN Utrecht voice: +31-(0)-30-68-94649 The Netherlands fax: +31-30-68-94649 The whole point of cooking is to get as much flavour out of the ingredients as possible. -- Delia Smith
