Hello,

I have setup a new Notification Target using SMTP to my internal server.

Everything works fine (test, backup notifications, ...).

But I have found that two sessions are openened for every mail.

Here is the smtp sessions on my mail server.

Code:
[23/May/2024 08:15:53][1192] {smtps} Task 196 handler BEGIN
[23/May/2024 08:15:53][1028] {smtps} Task 197 handler BEGIN
[23/May/2024 08:15:53][1192] {smtps} Task 196 handler starting
[23/May/2024 08:15:53][1028] {smtps} Task 197 handler starting
