We are currently using a webapp that generates outbound emails, but are experiencing a few issues.
When the system sends an email directly to a Gmail user (eg. john.smith@domain.com) it is received fine. If the email is sent to a Google apps group (eg. finance@domain.com) it is never received by any of the group members.
The "finance@domain.com" propogates to approximately 6 users. I have reviewed the Spam folder for a few of them and the email still isn't there either.
If the Google engine does indeed classify the inbound email as spam for a Google group, what does it do with it?
Here's a snippet of the header showing that SPF passes:
Received-SPF: pass (google.com: domain of XXXX designates XXX.XXX.XXX.XXX as permitted sender) client-ip=XXXXX;
Authentication-Results: mx.google.com;
spf=pass (google.com: domain of XXXX designates XXX.XXX.XXX.XXX as permitted sender) smtp.mail=XXXXXXX
