Do not reveive e-mails | SMTP Config

[Sinic98]

Hello,

I have installed the Ubuntu 20.4 LTS on my RPI 4 8GB. For that, I used the instructions from here to install Rocket.Chat on it.

Unfortunately, I can not receive any e-mail which was sent by my rocket.chat server. First I tried it with a Microsoft Exchange server. Then I tried it with Gmail. Did also not work.

The only thing I want to do is to invite other users.

The SMTP config is as follows:
Protocol: smtps
Host: smtp.gmail.com
Port: 587
IgnoreTLS disabled
Pool enabled

• my credentials

Do you know what could be the reason for that?

Thanks!!

Regards,
Sinic
