use IMAP instead of MTA forwarding [feature request]

[n1trux]

It would be awesome if you could also integrate an easy way to do this without changing the mail server config.

E.g. enter IMAP and SMTP details and create a systemd timer/cronjob to fetch mails every 10 minutes, then forward based on the mailing list settings.

While this would require storing every already received message ID in a database (or utilising IMAP "read" flags), it'd also be a super easy way to manage mailinglists which is not available in any other mailing list manager.

Allow pulling incoming email will make nanolist much easier to setup.

I am looking for a mailing list for my VPN service. There would be less than 10 subscribers, so I am looking for a simple mailing list service that easy to setup and easy to manage:)
