Question

What could be the reasons duplicate emails are sent from Ubuntu 20.04

I used DO LAMP for Sendy. Sendy is a newsletter program and it uses AWS SES and I set it up correctly.

It sends a confirm-email ONCE and an email-confirmed email TWICE.
The Message-IDs are different and one is created after 1 second.

According to the developer, it should send it only once.

I disabled all cron-jobs, but I still get duplicates.

I’m not sure what could be the causes.

I’m open to any suggestions. Please let me know.

My server has the following ufw.

To Action From
443/tcp ALLOW IN Anywhere
80/tcp ALLOW IN Anywhere
22/tcp ALLOW IN my-ip-address
22/tcp ALLOW IN my-ip-address
25/tcp ALLOW IN Anywhere
110/tcp ALLOW IN Anywhere
443/tcp (v6) ALLOW IN Anywhere (v6)
80/tcp (v6) ALLOW IN Anywhere (v6)
25/tcp (v6) ALLOW IN Anywhere (v6)
110/tcp (v6) ALLOW IN Anywhere (v6)

Hi there,

In theory, if there are no corn jobs added, no emails should go through. Could you share the current cron jobs that you have set up?

I’ve noticed a few different articles where people reported the same problem due to the corn job running too frequently.
