My current docker-compose config is:
I have tested sending an e-mail from my postfix server (in MAIL_URL above), and it works. However, when I try to invite users in the application, it says sending e-mails failed. This was working previously (previous container version), but how would one recommend debugging this? The logs from docker don't show anything regarding failed e-mails. The container can ping the mail server, but doesn't have any utilities to test sending mail installed on it.
