I work for a site where incoming mail is a big part of our daily
operations. I have installed spamprobe on all of our user
accounts, and find that it generally works very well.
We accept a lot of attachments, however, from a lot of different
people. Spamprobe is great because it does not scan
attachments. The people who send us attachments are not always
very computer literate, however, and some of them send us
attachments within the message body. That means message
bodies of 1 Meg and up.
I would like to see a built-in "head" feature with spamprobe, so
that one could specify the maximum number of lines to scan. The
problem with simply piping the input through "head", is that it is
possible for an attachment to be included near the top, and so the
first lines of the encoded attachment are piped through to
spamprobe, which disregards these.
