Ah, correction. It will work from my domain (google apps hosted) if I set CF7 to send to my regular gmail.com address. But it won’t work from my site (at my domain) – to my google apps email for the same domain. So for instance:
my-wordpress-site.com > contact form 7 > [email protected] (NOT working if [email protected] is hosted at google apps)
my-wordpress-site.com > contact form 7 > [email protected] (YES)
my-wordpress-site.com > contact form 7 > [email protected] (YES)
