DSN without attachment?
in [Postfix]
|
From: Markus Schwengel on 12 May 2010 10:28 Hi all, I'm using postfix 2.4.6 and clamav-milter 0.9.6 to scan mails for viruses. clamav-milter is set to reject mails in case of a virus found. Postfix then sends a DSN to the sender with the original mail (and the virus) attached. Is there a way to tell postfix to not include the attachment in it's DSN? cheers, Markus

If you're using clamav-milter postfix will reject the mail with a milter-reject: log entry and no DSN is sent. So, what are you really doing? http://www.postfix.org/DEBUG_README.html#mail -- Noel Jones

Is this not a DSN generated by postfix? I'm confused... |
