AWS Lightsail - PTR & SMTP
Hi Guys New to AWS Lightsail. I have created a WordPress instance with Lightsail. I need some help as I am new and not very savvy in this case. The I have associated a static IP to the WordPress site and it is running fine. I am having some issue with email rejection and not sure why. Something to do with PTR and SMTP. The domain is pointing to Office 365 Email using "Microsoft" Name Servers. Basically they are hosting the DNS records, from there the domain is pointing to Lightsail instance using and IP "A" Record. That is all. Now I just want to know if this cause any issues and or if I need to implement anything else also who to use PRT and where. Appreciate any help in advance. Ben
Deploy Exchange Server 2016 into an existing VPC
I would like to deploy two exchange servers in AWS into an existing VPC using the cloud formation template provided in GitHub. I do have an existing active directory instance, but the template in GitHub includes active directory deployment. I want to isolate that part of the template only to include exchange server deployment. Is this possible and do I need to store the required PowerShell scripts and cmdlets in a new S3 bucket? https://github.com/aws-quickstart/quickstart-microsoft-exchange/blob/main/templates/exchange.template.yaml
