We have multiple domains in our Google apps (example1.com, example2.com). Emails and aliases for example1.com are working ok - mail sent to email@example.com is redirected to firstname.lastname@example.org.
I'm trying to set an alias email@example.com and firstname.lastname@example.org to be redirected to email@example.com - this is an option in user settings. But the problem is that when I try to send an email it bounces back.
Mail delivery failed: returning message to sender A message that you sent could not be delivered to one or more of its recipients. This is a permanent error. The following address(es) failed...
I checked it here: http://mxtoolbox.com/ and I get this error:
550-5.1.1 The email account that you tried to reach does not exist. Please try 550-5.1.1 double-checking the recipient's email address for typos or 550-5.1.1 unnecessary spaces. Learn more at 550 5.1.1 http://support.google.com/mail/bin/answer.py?answer=6596
Any ideas why it's not working?
EDIT: If I send an email from a domain on our server (for example: firstname.lastname@example.org or email@example.com) to any alias at example2.com, it also won't be received. But from other emails on other servers it works fine.
