Hi I am finding a similar issue.
wp vers. 3.4.2.
jetpack vers. 2.1.1.
I have a contact form that successfully sends emails to gmail and my own websites domain email but to the required email address, nothing.
I have all tested emails in the feedback dashboard in the admin.
Specifically though the site is hosted on my server however the domain is being forwarded elsewhere via its a record.
Could this be linked or is there a way around this?
I would appreciate your help on this.
Stuart
