No one helped me with my original problems, but I think that's because they thought I was a moron... BUT I still have faith... Here's what happens now when I send a message to myself (attached with one of the banned extensions) failure: 192.168.2.26_failed_after_I_sent_the_message./Remote_host_said:_554_mail_ser ver_permanently_rejected_message_(#5.3.0)/ Here's what I have as my 'qmail-queue' in /var/qmail/bin #!/bin/sh exec /var/qmail/bin/qmail-qfilter /var/qmail/bin/deny-filetypes If there's no 'banned' attachment, it goes through okay... and I receive a bounce saying 192.168.2.26 failed after I sent the message. Remote host said: 554 mail server permanently rejected message (#5.3.0) How do I get qmail-filter to add something about having a banned extension... ??? Again, I am using the qmail-qfilter program without using QMAILQUEUE ... Thanks!!!
