Intially we are thinking of a web ui to control the filtering rules though Sieve as a mail filtering language might work with some modifications like envelope sender/recipient based filtering and filtering by attachment names. I guess we have to wait and see what kind of power users would want.

Sieve/other mail server filtering implementations currently only target incoming mails, so I would be interested in knowing how you manage outgoing mail filtering if at all ?

From your emphasis on "a mailserver I control" I guess you are leaning towards the in premise version if you ever need this.

About the logo, as you guessed correctly it was a quick selection to get up and running and not the final version !
