Postfix header_checks and webpage validation
Are you sick and tired of all kinds of virus warning in your mail? It
would be nice to just bounce it back to the clueless sender at the MTA level, right? If you use Postfix you're in luck,
just use antiantivirus.txt as
header_checks and most of it should go away. There's a procmail version named antiantivirus_procmail.txt
too. They're both derived from SpamAssassin
and the checks it makes for “spamness”.
I've spent some time the last few days making sure my
web-pages are valid XHTML 1.1, and
since it was already XHTML 1.0 Strict
it wasn't really a big deal at all. The hardest part was upgrading tidy to version 2004-02-05 instead of
the ancient one in the OpenBSD ports tree. I should make a
www/tidy-devel port, as it is a quite different beast now.
Now I just need to figure out a way to use the suggestions in Mark Pilgrim's “The Road to XHTML 2.0: MIME Types” over at XML.com, it isn't as straightforward as it looks, at least not in my test setup here at home.
