Hi,
I'm quite sure this is near FAQ, but I didn't succeed trying guessing it
myself, nor looking through archives, so pls forgive my asking here -
What I'm trying to do, is put a perl filter just before qmail-local puts
its hands on mail. I moved qmail-local to qmail-local-orig and put in a
script named qmail-local, which calls the filter first.
Could you please tell me if it is possible to do this with a sh or perl
script? If yes, any hint will be highly appreciated, an example of script
which just does nothing and forwards mail to qmail-local-orig would be
great. I know I could write qmail-local replacement in C (qmail-lspawn.c &
qmail-local.c as inspiration), but I'd prefer the script solution now, if
possible.
The resulting flow would be like this:
qmail-lspawn --origmsg-> qmail-local --filteredmsg-> qmail-local-orig
The filter itself is simple one-pass always-success script, which just
scans attachements for .exe, .vbs, .. and adds .VIRUS extension, so that
nobody can simply click through the worms (yes I have such users here).
Yes, I'll make the script available (BSD) after some more testing.
Thanks,
