Due to a DMARC policy change by AOL, Yahoo, and AT&T/SBCGlobal in 2014 we cannot ensure the delivery of emails to either of these providers. (Example: firstname.lastname@example.org / email@example.com / firstname.lastname@example.org) For more information on the DMARC protocol visit http://dmarc.org/
For this reason we do not recommend using either an AOL, Yahoo or AT&T/SBCGlobal email account as the direct recipient on your VCG hosted website(s), whether it be a contact or form page. AOL also suggests that "… you switch to sending ‘and receiving’ mail from your own domain".

If VCG is hosting your DNS (Domain Name Servers) it is suggested that you create a SmarterMail email account and set it to forward to your AOL, Yahoo or AT&T/SBCGlobal account, and then white list your domain within these provider accounts to ensure deliver-ability.
You can then set this new account as your contact and/or form recipient in the MyVCG Portal. This will resolves the issue assuming the sender is not using an AOL, Yahoo or AT&T/SBCGlobal email address.*
* IMPORTANT: If the sender is using an AOL, Yahoo or AT&T/SBCGlobal account you need to review the email(s) within the SmarterMail webmail client. (mail.yourdomain.com).
