clamav-milter appends to message headers; should prepend

[Stephen Warren]

Binary package hint: clamav

clamav-milter adds the following headers to messages:

X-Virus-Scanned: clamav-milter 0.95.2 at severn.wwwdotorg.org
X-Virus-Status: Clean

which is great. However, these headers are appended to the set of headers in the message, rather than prepended. It'd be better if the new headers were prepended, so if the email gets routed through N servers, the clamav headers and "Received:" headers would intermingle in time order. This would better show where the message was virus-scanned.

There is a sample config file shipped in the source package (apt-get source clamav) that shows the config option to do it this way. Have a look at that (yes, this could be better documented.

Since somebody emailed me asking if this had been resolved and how, here's the information, for them and for Google:

In /etc/clamav/clamav-milter.conf, add/modify this setting:

AddHeader Add

See /usr/share/doc/clamav-milter/examples/clamav-milter.conf for details.

I think the Ubuntu/Debian package should ship /etc/clamav/clamav-milter.conf with that line included. I'm not even sure why the milter code allows any other setting; by corollary with the Received: header, it doesn't make sense to use "AddHeader Replace", which is the code's default apparently.
