I'm trying to add an alias to my Google Apps for Business Gmail account following this article:
https://support.google.com/mail/answer/22370?hl=en&ref_topic=3395757
But at the step 5 "Click Next Step >> and then click Send Verification. Gmail will send a verification message to your other email address to confirm that you own it." I'm always getting the following error, no matter what account I try to configure.
Is it a new feature of Google Apps for Business? A Bug? What can I do about it?
