Happy New Year to everybody!!

My domain is currently hosted on Google Apps, "domain.com".

I use the name "pmg.domain.com" on Proxmox, and everything works great. However, when I activate the "Verify Receivers" option, PMG sends an email "double-bounce@domain.com" to verify, but it fails:

Jan 3 11:30:38 pmg postfix / smtpd [18843]: NOQUEUE: reject: RCPT from pmg.domain.com [xxxx]: 450 4.1.1 <destiny@domain2.com>: Recipient address rejected: unverified address: host mail.domain2.com [yyyy] said: 550 5.1.0 <double-bounce@domain.com>: Sender address rejected: domain.com (in reply to RCPT TO command); from = <sender@domain3.com> to = <destiny@domain2.com> proto = ESMTP helo = <pmg.domain.com>

Any suggestions on what to do?
 
it seems that the next mail server rejectst the verification-email because it is sent from @domain.com, maybe you can whitelist the pmg host in google apps somehow?
