E-mail activation error for multisite

I am testing and documenting new multisite creation. When I get to this point:

Congratulations! Your new site, Test One Now, is almost ready.

But, before you can start using your site, you must activate it.

Check your inbox at [myemail] and click the link given.

If you do not activate your site within two days, you will have to sign up again.

Still waiting for your email?

If you haven’t received your email yet, there are a number of things you can do:

Wait a little longer. Sometimes delivery of email can be delayed by processes outside of our control.

Check the junk or spam folder of your email client. Sometime emails wind up there by mistake.

Have you entered your email correctly? You have entered[myemail], if it’s incorrect, you will not receive your email.

Is there make any settings in Host gator
