Hi,
We have an issue with integrating a spam filter into postfix. When a
mail enters the mail system a loop start between postfix and dspam. And
I don't know why the loop start because when the mail returns to postfix
(localhost:10026) we override mailbox_transport and the mail should be
delivered with the mailbox_command option (dovecot). What am I doing
wrong?
Thanks,
Martijn
