no, it's not possible to 'trigger' the junk filter for testing, except by
receiving new mail. you can certainly make a rule to delete anything with
[spam] or whatever in the subject line or header.

Due to a huge increase in junk mail in the past few weeks I have
configured a
third-party product as a spam filter. It works well, but to get it to play
happily with Outlook it seems necessary to create a rule for every mailbox
so
that a particular header is checked, then the spam that would have escaped
the default junk mail filtering is moved to the Junk E-mail folder.

Assuming I can add headers and prefix the subject line, is there a way I
can
make Outlook 2003 SP2 recognise mail as spam and have it trigger the
normal
junk mail filter? I imagine that for testing purposes there is such a
feature
built in.
