Resolved AWS EC2 STMP Woes - Amazon have authorised me but I still cannot send mail

[chrisjako]

Server operating system version

Ubuntu 22.04.2 LTS

Plesk version and microupdate number

Plesk Obsidian 18.0.51 Update 1

Tryin to setup SMTP on port 465 Outlook gives me the attached issue



I contact AWS to get limits removed and they repsonsed with:

Hello,

We approved your request for the removal of the EC2 email sending limitations on your Amazon Web Services account for the following regionseu-west-2! If you requested removal of email sending limits on any other Amazon Elastic IPs, they've also been removed.

Plesk also no longer shows the warning about the mail server being blocked

Firewall on AWS EC2 is set to allow 25,587,465

What am I doing wrong?

First try with other software that doesn't hide the actual problem.
Second, email sending limits are for sending mail from the server. Using Outlook on port 465, you are trying to send mail to the server. Different direction, different filter.

setting to starttls and port 587 fixed the issue
