Dear Helper,

whenever I try to invite someone for bonus mailbox for my domain (iniciativapublicitaria.com); it says: 

"You can start referring other domains only after you change the mx records of your domain" 

But I'm pointing to mx.zohomail.com and  mx2.zohomail.com since yesterday. And I'm able to send/receive mails from existing mail accounts.

Please fix the issue and let me avail bonus mailbox at your earliest. 

Please help.  Thanks.

Leandro
