Removing User Agent from message headers

[Anhad]

How to stop this:
User-Agent: Roundcube Webmail/1.1.4

From appearing in the message headers ?

I'm using dovecot/exim setup with roundcube.

Modify 'useragent' option in config.

Can't find the useragent var in the config file. Which config are you talking about ?

If you can't find it then add it. See defaults.inc.php for an example.
