# mailpopbox

Mailpopbox is a combination delivery SMTP server and POP mailbox. The purpose is to act as a
catch-all delivery server for an MX domain. All messages that it receives are deposited into a
single mailbox, which can then be accessed using the POP3 protocol.

## TLS Support

TLS is recommended in production environments. To facilitate live-reloading of certificates, you can
send a running instance SIGHUP.
