"mail to program disallowed" problem

[Martin Konold <konold@fiwi02.wiwi.uni-tuebingen.de>]

Hi Matti et al.,

Thanks for the great zmailer. Unfortunately do to my missunderstandigs I
ran into trouble...

Does anyone know what went wrong in this case?

<local pipe.listname@fiwi02.wiwi.uni-tuebingen.de "|exec
/var/list/.bin/flist listname" 65534>: mail to program disallowed

And /var/log/mail/scheduler shows
19971125223915 /usr/ta/mailbox: 307291/210//error2 mail to program
disallowed
19971125224025 /usr/ta/mailbox: 307291/189//error2 mail to program
disallowed
19971125224215 /usr/ta/mailbox: 307307/127//error2 mail to program
disallowed
19971125224646 /usr/ta/mailbox: 307307/133//error2 mail to program
disallowed
19971125225117 /usr/ta/mailbox: 307307/210//error2 mail to program
disallowed


Thanks,
