Ok, this is probably obvious but for some reason I am not coming up with an answer to this. I have tried google and what man pages that I could think up to look at so if there is a man page with this info or a google search that provides an answer please point me in the right direction (because apparently I missed it).
Here is my problem. Our main email server is hosted by another company. This company also has a co-lo facility where we put our web servers etc. Recently, they have switched to a new email system and now I am not receiving the daily emails (or insecure etc.) from our co-loed boxes. Some digging found that this new mail system checks to see if the from address on an email is a valid email address, and it isn't. For instance, the daily email from our "foo" server would come from: [email protected] The email server doesn't have an account for that email address so the email is rejected. How would I go about telling each of our co-loed boxes to use a particular email address as the from address for stuff like daily email etc. so that it will look to the email server like it is coming from a valid email address and thus accept the email? Or is there a better solution that I haven't come up with? Thank you for your time. Stuart van Zee [email protected]
