Can receive, but not send emails on AWS Lightsail with Plesk - amazon-web-services

I just added my WordPress website to AWS Lightsail and wanted to set up my mail accounts as well.
Receiving mails from my Google Mail account works, BUT
sending mails to my Google Mail account does not work.
I receive emails that I send from hi#mydomain.com to bye#mydomain.com.
I opened all recommended ports by Plesk and can only receive emails.
Enabling SMTP service on port 587 on all IP addresses in the server-wide settings does not solve my problem.
What should I do now?

AWS closed port 25 by default (Still open for tools that check ports). Nevertheless, the support finally replied and told me that they remove it manually to prevent spam.
You can remove the limit of your Lightsail instance with the following form: https://aws.amazon.com/forms/ec2-email-limit-rdns-request

For security reasons Google blocks SMTP traffic and that is why you can't send email:
By default, Compute Engine allows outbound connections on all ports
but port 25, which is blocked because of the risk of abuse. All other
ports are open, including ports 587 and 465.
See also the documentation what kind of traffic gets always blocked by default in GCP (and you can't change it).
The only way to semd emails from you GCP instances is to use trusted 3rd party tools such as: SendGrid, Mailgun, or Mailjet.
Have a look at the documentation on how to send emails from GCP VM's, which provider is best suited for you and how to configure specific service.

Email is not working in AWS lightsail with plesk controlpanel

I tried with php mail function and the email is not sent. I activated the port 25 in the aws instance network setting but no uses.
Checked the mail settings option in the plesk Controlpanel, I got the following message
You cannot send emails from Plesk because outbound connections on TCP port 25 is blocked. Check the firewall settings or contact your hosting provider.
Please give the suggestion, how to resolve it.
You need to request to amazon to open that port, by default it is blocked..After request they open it.
Here is the link to request

AWS EC2 - reverse DNS and port 25 blocked by AWS

I am trying to set up my own Email server on EC2 instance, but facing issue related reverse DNS and SMTP port 25:
Incoming Mail (SMTP/postfix) is running but is not publicly accessible at X.X.X.X:25.
Outbound mail (SMTP port 25) seems to be blocked by your network. You will not be able to send any mail. Many residential networks block port 25 to prevent hijacked machines from being able to send spam. A quick connection test to Google's mail server on port 25 failed.
Your box's reverse DNS is currently ec2-x-x-x-x.ap-south-1.compute.amazonaws.com, but it should be mail.xyz.com. Your ISP or cloud provider will have instructions on setting up reverse DNS for your box.
By googling I found Request to remove email sending limitations link, I requested by this form to AWS, but didn't getting any solution.
Please guide me on this.

If you're still looking for guidance on how to setup an email server using Amazon EC2, I've written a guide for it. Even though some find using ec2 for email to be a hassle it doesn't have to be for you.

Here are some details about what the configuration will give you;
The system uses:
-Postfix as the smtp agent
-Dovecot as the client-side connect and mailbox manager
-Postgresql database to handle mail users, mail transports and the Spamassassin database
-Amavis (w/ Clamav & Spamassassin) for protection against viruses sent through email, and to facilitate an adaptive spam detection system that learns and corrects its behavior for each individual user
-Spamassassin as the spam filter and bayes to learn spam from ham and ham from spam
-Apache as the web setup, enables http & https connections to your site
-Squirrelmail as the default webmail. After the server is setup you will be able to check your email on yourdomain.com/mail from any browser on any device
The system supports:
-Multiple transports for different domain
Good luck, and let me know if I can clarify anything.
