Not getting email on form submit

I managed to get it work by changing emailsender to my email address in the snippet call. Is there anyway way for it to get the email address from the config instead.

You can either leave it out altogether, or use [(emailsender)]. The $modx->config[] array is only for use in PHP code (snippets, plugins, etc). But if you leave out the &to parameter eForm will automatically pick it up from the config (using $modx->config[’emailsender’], in the PHP code)
