Contact Form email address set in the plugin's setting being changed by Linode server? I've used the contact form plugin many times with no issues. However I have a site set up on a Linode server and for some reason the from address that I have added in the contact form settings e.g. contactus@mydomain.com is being changed to contactus@localhost.localdomain when the email comes through.

Anyone any ideas what is causing this. I'm thinking it's a server setting but wanted to check the plugin wasn't causing anything weird to happen as well.

Cheers
Generally I've been dissatisfied with the craft cms contact form plugin. Fortunately, this doesn't need to be handled with the CMS. I've been using third party tools such as Formbucket to handle form submissions for several reasons.


Reliability is extremely important. Most clients will not tolerate any mistakes regarding lead generation in contact forms.
Feature rich. Craft's contact form plugin is very barebones and ugly. With formbucket and other form submission collection tools, you can add as many fields as you want instead of segmenting message. There is also honeypot and recaptcha fields to keep out spam.


I know this is probably not the answer you were looking for, and I wish you the best with getting it to work, just wanted to let you know how i've been doing it. 

PS: I don't work for Formbucket.
