Access Squirrelmail while DNS propagates

Hi There, I’m able to access squirrelmail but my client is not, I assume this is because the DNS is still propagating.

My question is, does anyone know how to access squirrelmail while the DNS propagates, without using the webmail sub domain?

Thanks.

Hi There, not sure if this is useful for anyone but if you need to know how to do this you can access webmail via - webmail.dreamhost.com
