On my Exchange server I can drop appropriately formatted text files in the "pickup" directory and Exchange will process them.
I'd like to split this bulk mailing functionality onto another box to protect our business mail IP from the bumpy ride that our monthly newsletter gives us.
I should note at this point that the mailing is opt-in with an opt out link included and only goes to people who pay to be a member of our organisation
The ideal solution for me would be to add a linux box to use just for this purpose so we're not paying for Exchange licenses.
So is there a linux equivalent of the Exchange pickup directory?
