Wanting to temporarily change the default address for all accounts to :blackhole in order to slow down a dictionary attack on my servers. I know I can go into each accounts cpanel and manually change the default address there, but looking for a way to do this for all accounts at once. Thanks,

  I found the following post from several years ago, but it's not working. I'm getting -bash: replace: command not found

  Also found this post from a couple of years ago but the OP never provided a script. Honestly it would be easier for me to do them manually that trying to figure out how to write a script. Hoping there might be an easier way since 2 years ago.

  maybe just delete and append the line. here's a couple commands: sed '/^*:/d' -i /etc/valiases/* sed '1 a*: :blackhole:' -i /etc/valiases/*

  Thank you @vanessa, I already went the manual route, but I'll try this when I get ready to switch back to :fail.
