I have setup a web form that sends out a intro email to leads.

This works fine, however the intro emails are being placed in customer's spam boxes so unless they check they don't get them.

There are a couple of issues that might trip up the spam filters:-

1. My email on here is julian@over... that is automatically picked up on the setup for the autoresponder, but I have set the responder to reply to sales@over...  This disparity may cause issues - annoyingly I have setup the sales@over... address under the CRM setup, but it doesn't give me an option to use it in the autoresponder setup which is a pain.

2. The emails will be going out via a Zoho SMTP server which isn't necessarily an authorised source for my domains.

Now, if I setup Zoho Mail so that it collects from and sends through my mail server, will the autoresponder emails also go through my mail server?

Many thanks.
