Dear developers and maintainers,
Docker Mailserver is fantastic project, thank you very much for it! ;-)
Could you please help me with one question I didn't find an answer to? I searched in Docs and in github issues...
A few days ago I installed Docker Mailserver and I sent just a few e-mails from it to my own address to verify everything is working fine. Yesterday I received a concerning e-mail from linode.com where I'm hosting the server.
I think there are two options.
a) The e-mail it's wrong and I should not worry.
b) Some bot searching for 25/tcp open ports hacked into the mailserver. When I set up my accounts I used a very strong password but I'm slightly worried anyway.
Could you please tell me the best way to monitor all outgoing messages? It's not a privacy concern since I'm the only user of the server...
Thank you.
Billy
