Outgoing Mail (SMTP) Servers usually restrict who can send mail through them. Some ISPs restrict the use of their outgoing mail servers to IP addresses that it owns.
This means that you may not receive email notifications when a user fills out the request form on your site. Unfortunately this is beyond our control. Please remember to login to your CRM System to ensure that you do not miss any client requests. You can configure an email address (firstname.lastname@example.org) with us and the email notification feature will function properly. Please contact us if you have any questions.
