Hello all;
Jay Fougere, IT Manager for iEntry here.
There are several issues at stake here. We cannot change the 'from' and 'return' domain because of the way we handle bounces etc. ientrynetwork.net has a separate mx record from all of our other domains because bounces are sent back to our mailing system directly. Any specific RFC addresses, such as support@ and abuse@ are forwarded from the mail system to our regular office email servers.
Regardless, many mail servers send mail with different 'return' and 'from' domains than the actual server domain name. This is perfectly legitimate. Google themselves do this as a matter of fact. For employees on the road, we have set up ientryinc.com which is hosted by gmail a.k.a. google. Any email sent from one of these accounts has a return address of 'someuser@ientryinc.com' however if you look at the header information the email originates on a google.com server (See below, slightly edited to remove IPs and email addresses):

As you can see, the 'from' and 'return' addresses are from 'ientryinc.com' addresses while the servers are all google.com servers.
Lastly, we have published SPF records that are in fact correct for the IP addresses and domain names involved.
This is something that is happening on Googles end and we are trying to resolve the issue.
