When using this, bots are using the mailserver to send out SPAM.

Are there any way you could tell the mailserver, only to accept outgoing connections from localhost?

@geek-at commented on GitHub (Sep 30, 2019):

Wow you scared me for a second.

Outgoing mail is not supported on the mail script. It looks like spammers are sending because your the server acts like it is sending but it's not. It just stores the data locally and then exits.

I have confirmed this now using tcpdump.
