for (i = 0; i < document.f.t.length; i++) {document.f.t[i].checked = true;}

You can use this script, if you'd like to post your email address to your homepage, but don't want to see it picked up by spammers.

Just run it in your onload event handler and mark emails in your HTML as:

markos at gaivo dot net

This way they are still recognizable by those who don't use javascript.

If you need help or want to discuss this code, please do it on my blog.

Clearing out a bunch of spam with spoofed emails that were bounced back to some poor guy with a catchall email

We don't really want to delete them all just in case.



cd /usr/local/scratch/

mkdir junk

find /var/spool/postfix -exec grep "somediscernible-feature.com" '{}' \; | awk '{print($3)}' | xargs -J X mv X ./junk/

The "find" produces



Binary file /var/spool/postfix/active/D/D8832E38 matches

Binary file /var/spool/postfix/active/D/D78EC1C72 matches

Binary file /var/spool/postfix/active/D/D593D279D matches

Binary file /var/spool/postfix/active/D/D0EB32833 matches

The awk



/var/spool/postfix/active/D/D8832E38

/var/spool/postfix/active/D/D78EC1C72

/var/spool/postfix/active/D/D593D279D

/var/spool/postfix/active/D/D0EB32833

And then the mv, moves it.
