9/20    Christ, I have gotten literally hundreds of these emails purporting
        to be a Microsoft patch.  I am running SpamAssassin, but this is well
        crafted.  Yet, I read it is "easy to filter out" if you are running
        a mail server.  Cannot soda block this?
        \_ It would indeed be "easy" to block this at a server level, but, to
           \_ The following rules seem to work for me:
                :0 w:
                * ^Subject:.*(Microsoft|Net).*(Security|Critical|Patch).*
                /dev/null

                :0 Dw:
                * ^SUBJECT.*
                /dev/null
                \_ Maybe I'm reading this wrong but wouldn't this second one
                  delete all your mail sight unseen?
                  \_ hmm... I guess that's one way to keep all the spam out
                  \_ D -> case sensitive match. Most of the M$ spam uses
                     SUBJECT: as the subject header, so I just trash that.
                     Mail that uses Subject: as the subject header still
                     gets through.
           \_ The current outbreak finally got me to get procmail going.
              Here's a recipe I got from Usenet that trashes all messages
              with executable attachments:
               :0B
               * ^Content-[-a-z0-9_]+:.*($[     ].*)*=[         ]*($[   ]+)*"?[^\
"]*\.(ad[ep]|asd|asx|bat|chm|cil|cmd|com|dat|dll|dot|eml|exe|hlp|hta|inf|jse?|ln\

efh]|xl[wt]|\{[0-9a-f-]+\})\>
               /dev/null
              \_ As long as you're going to filter every obscure .ext you might
                 as well toss in .btm.
           go back to the old mantra, this is a volunteer-run machine.  Keeping
           up with spam/virus screen has become a full time position in many
           organizations.  With the csua, as is stated on the application form,
           you're expected to have some sort of a clue on how to deal with this
           stuff.  Also, to start a new mantra, server side email screening
           attempts almost always piss off more people than they please.  Read
           up on procmail. --scotsman
           \_ otoh, it's in a sysadmin's interest to block the major windows
              worms, because there are bound to be people who can't learn
              procmail in the hour in might take for their quotas to fill up.
              besides, worm mail is a specific target that's easy enough to
              handle and there isn't a new outbreak every day.
              \_ Doesn't matter.  Slippery slope and all that.  Take some
                 personal responsibility (remember the part about having some
                 sort of clue?), educate yourself, and be glad you have access
                 to a machine like this.  There are some incredible technical/
                 personal/professional networking oppurtunities through the
                 csua, but not when everyone gets bitchy because of inflated
                 expectations. --scotsman
                 \_ You're sounding very libertarian or republican with all
                    that BushCo talk of personal responsibility.
                    \_ there's a wide distinction between a student
                       organisation at a university and the federal
                       government.  Amusing troll, though.  --scotsman
                       \_ So now you're saying we should take personal
                          responsibility at the personal level but at the
                          government level we should make someone else take
                          care of us?  Call it a troll if you like.  It doesn't
                          change the fact that you were espousing libertarian
                          ideals and then knee-jerked away when caught.
                          \_ Hardly.  When you signed on to this organisation,
                             you agreed to clauses that said basically you
                             wouldn't be a pest.  My personal politics do
                             not enter into this discussion at all.  My views
                             of civic governance have next to no relation to
                             my view of the csua (of which I was a governing
                             member for 3[?] semesters. --scotsman
                             \_ Asking the csua admins to filter some crap is
                                helpful to everyone, not being a pest.  You
                                did a nice dance but you're still a libertarian
                                but I think you're still ok despite that.

8/16    Why does my Y! mail account always full of unfiltered spam
        mails (and they're obviously spams)? Why can't they do
        a better job like Google mail? Why does Y! mail charge
        for exporting email? Google mail doesn't do that.

7/17    Thanks to steven, et al. for restoring Soda. In lieu of www.csua providing
        status, could there be a text file with current status and future plans.
        I'm wondering if SpamAssassin is obsolete (and my procmailrc and scripts)
        and won't be restored, and what's filtering spam now.  thanks!
