SMTP delivery in addition to Postmark?

Hi Etke team!

We're a small ISP over here which does not use commercial services for Internet things. This means we cannot use Postmark, but do have our own SMTP service available.

Are there plans for Buscarron to support other delivery mechanisms, other than the email API, such as SMTP?

This would be highly welcomed, and also free the free software from ties to commercial vendors (:

Thanks in advance!

Jon
