andsens's questions

I am maintaining an ec2 bootstrapping script for debian squeeze on github. The setup has become very minimal and I try to justify all my changes to the standard setup.

Currently I am wondering whether there would be any problem with disabling all TTYs via /etc/inittab.
People log in to an AMI via ssh anyways, which spawns its own shell.
Is there anything that can be installed on the server which expects a TTY to be present?
Would XEN have a problem with this in the long run?

p.s.: Github issue here

currently my acl check_mail part looks like this:

deny  
    message = The sender name must be the same as the login id  
    condition = ${if eq{$sender_address}{$authenticated_id}{no}{yes}}

However I would like to verify the domain only.
How do I strip that part out of the variables?
