Problem :
I am running the Adobe Connect 9 installer on my server and I am unable to go beyond the mail settings window.
My SMTP host works fine with other applications, but it somehow doesn’t work with the Adobe Connect. I am putting a valid email address under System Email field, however, it still comes up with an “Invalid Email ” error.

Error-Screenshot
Environment :
Adobe Connect 9.0.0.1 Licensed
Reason :
If your company has a three level domain email address or greater and you are trying to configure that with Adobe Connect 9 installer; like, xyz@abc.xx.xx, you might run into this issue.
Solution :
This has been identified as a known issue in the Connect 9 installer. Here’s how we can workaround this & complete the install :
1- Run the Connect 9 installer normally until you get to the Mail Settings window
2- Leave all the SMTP Settings fields empty
3- Put a two level test email address in the System email & Support email address fields, like, test@test.com
4- Carry on with the rest of the installation steps and complete the installation.
5- You would encounter the same issue on Create Administrator screen. You may apply the same workaround there as well.
6- Once the installation completes successfully, open the Connect console page, http://localhost:8510/console
7- Open the Server settings page & put the values of your valid smtp server settings and email address under Mail Settings section now.
8- You will be able to enter the correct details(three level or greater domain) of your smtp server now.
9- Contact support for any help or questions.

This was helpful. Thanks
This information was useful to get us past the install “stall”, but subsequent attempts to correct the fake data fail — the email server name and email addresses for our institution still are not deemed to be acceptable. Any further insights would be helpful.
