Hello,
I have spent a lot of time searching mail archives and google for an issue
I've been having with the attachment backend included with smtp-vilter. I
installed the OpenBSD 3.8 port, as well as the package, and had the same
problem in both. If I missed a relevant thread or some docs, I would be
happy to be directed to them.
The smtp-vilter does not seem to read attachment.conf. Any time I send a
test attachment, regardless of whether it is specified in attachment.conf,
the attachment is removed, and the message "Vaporized an unwelcome
attachment" is inserted. I have also commented out the
content-type=application/octet-stream line, with no effect. The fact that
changes to attachment.conf do not change the behavior, and that the
attachment-notification file is ignored have led me to believe that the
attachment backend is simply implementing its default settings, and that
the octet-stream content-type is being triggered. I found the "vaporized"
message in vilter-attachment.c but any further code examination is really
out of my league.
clamd works perfectly, and I don't see any other indications of problems.
I'd appreciate any insight anyone could offer. conf snippets and such are
included below.
Thanks,
Steve
