Squirrelmail Server Signature

[edmund81]

Is there any way to set a server wide signature on squirrelmail that will be attatched to EVERY email sent via the interface? I believe x10 does it to avoid liability for spam (?), though this might actually be on the mail server, but how can I do it on my own server. Thanks for your help.

but why do you need the server side signature.
I am just curious how would it help regarding sending emails to subsribers?

It was to secure it a bit, but I've now installed roundcube so that it automatically adds the domain to the login. This basically means that only emails on my domain can access it, as before anybody who had a gmail account could send emails through it.
