I want to prevent, that my users can execute
programms from the procmailrc. It should be even
impossible to pipe a incoming mail to an other
program.
Is there a possibility to compile procmail in
a way that only allow to filter mails to other
folders?
Look at the RESTRICT_EXEC option in your config.h file prior to
compilation. Newer versions of procmail (post 3.12) allow you to specify
the highest UID allowed to fork programs; pre-3.12 versions turn it off
entirely unless you use the unofficial patch at
http://mirror.ncsa.uiuc.edu/procmail/patches/smrsh-like.patch
Does a web based tool exist to configure a user
specific .procmailrc?
Take a look at the "dotfile generator." It's supposed to
be at
http://www.imada.ou.dk/~blackie/dotfile/
but I can't seem to connect right now. I also don't know if it has full
Web support yet, although it was in the works a while back.
