Users can't send mail

mkindi

Hello, I have managed to install the mailcow on my VPS and added the domain and some users but now the user can only receive mails but can not send them. I am new to this service as a web developer I thought I needed at least to test this out for future use

And check if your VPS provider allows for port 25 outgoing. Some do only after you request that.
