How to configure an email receiver?

[uebmaster]

i have been trying to set up ticket creation via email and i have not been able to get it, i already created an app password on my gmail account and i am using the following receiver setup:

in the gmail security panel it tells me that there was a connection attempt but it does not receive anything, in glpi when checking if there are new emails it sends me the following message:

My docker-compose file is the next:

I'm using an external network cause i'm using Nginx Proxy Manager.

I commented the volume

• /etc/timezone:/etc/timezone:ro

Cause i'm running docker in rocky linux and is the only way that the container runs.

Thanks in advance.
