I know there are a lot of posts out there about the notification system and mail not sending, but I've been unable to find the information I'm looking for so I decided to create a new post.
In short, I need the sending server IP or mail server name that Gravity Forms would use to send notifications. Is this something that would be specific to my site's hosting? I need to find it to whitelist it on the Exchange server that handles the emails for the site.
More details...
I have a site whose website and email hosting are separate. There is an Exchange server in use for the email and it is run by a separate company than the hosting for the website. We have an issue where the forms will not send notifications to emails that are on the Exchange server (ending with @sitedomain.com). The forms send notifications fine to external email addresses.
I contacted the Exchange server company and they said that it's because they have blocked all emails sent to the Exchange server that use the site's domain. In theory that should be fine since all the email is controlled on their end, and there shouldn't be any external emails using the site's domain. However, these forms would be using the site's domain. So, in turn, the forms get blocked sending to emails to the Exchange server.
Help?
