[qmailadmin] Spam filtering and forward revisited

[Michael Shell]

 Hello,

I'd like to know what contents are allowed in the forward field of
qmailadmin - specifically as it relates to spam filtering.

Suppose we want to add a line such as this to the forward
field (on a site that hosts many virtual domains):


|preline /usr/local/bin/maildrop /mail/domains/0/mydomain.com/.spamfilter


but this won't work (at least not under 1.2.0). This is probably
due to security concerns - there is a related post on this
topic recently:

http://www.mail-archive.com/qmailadmin@inter7.com/msg06124.html

So, is there a better/alternative approach? Are there some new features
in later (post 1.2.0) or that are being planned for future versions
that might be of help? Although it might not be desirable to allow users
to put anything they want in the forward field, there should be a way to
support at least some form of spam-test-based forwarding. One approach
might be to allow users a way to select from a choice of valid lines
pre-created by the sysadmin.


 Any suggestions or elaboration would be helpful.
 

 Thanks in advance,

 Mike Shell
