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

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
i've configured a mail server on my was ec2 which is linux 2 ami. But unfortunately whenever I try to send a mail from my server to a gmail account or yahoo account the maillog show me that connection timed out. I've created the following steps
created a subdomain named mail.domain.com pointed to my AWS Elastic Load Balancer on route 53
installed postfix
added my_domain = domain.com and hostname = mail.domain.com inet_protocol = ipv4
created my hostname as mail.domain.com
I have checked the ports 25 is running and it is also allowed on my aws security groups.
mail status on log is deferred
Now I really need to setup the mail server but I am not being able to create it. Can anyone help me?
Try to remove SMTP throttling. You can learn more about it below.
AWS blocks outbound traffic on port 25 (SMTP) of all EC2 instances and Lambda functions by default. If you want to send outbound traffic on port 25, you can request for this restriction to be removed.

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.
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.
I had my web app running in EC2 instance(AWS server 1). I have another AWS server 2 where the DB is. I had a verified domain and verified recipient test email address and emails were going out well. One day I did Elastic IP so that AWS 1 talk to AWS 2 for some other purpose. Not sure if that caused the issue. Now I reverted AWS 1 to normal Ipv4 address(removed Elastic IP) and all over my app and for SSH I use normal IPv4 address.
As per other posts, I also contacted AWS and increased the sending
limit.
I also set the outbound rules SMTP and SMTPS. None seems to
be working.
If I run the web app in my localhost with same SES
credentials, emails are sent out. Only when my web app is in Amazon EC2 then emails are not being sent out.
Following is the error that I am getting.
Unable to execute HTTP request: Connect to email.us-west-2.amazonaws.com:443 [email.us-west-2.amazonaws.com/52.94.209.0] failed: connect timed out
It's been 2 days and I am scratching my head to get it resolved. Please help.
PS: As per request, here are the outbound rules
Type : MYSQL/Aurora
Protocol: TCP
Port Range: 3306
Destination : //MyIP
I don't have any other outbound rule.
