I need API access to obtain sender and destination address of mailbox item and then decide how to dispense with it, either delete, retrieve or forward to a different destination. "Destination" may involve dozens of addresses. Reply address may be changed.
To minimize storage and costs, any item over 24 hours old can be deleted.
Thank you for the suggestion.
My clients have a lot of hourly employees that they need to communicate with but for privacy reasons, they don't necessarily want to use a corporate or private email address.
For example, a manager may want to use his private phone to send an email to a group of employees. Any replies would be routed to his secretary at the office --- with all addresses remaining semi-anonymous. My software will handle all this with the help of your service.
I currently have several hundred clients with a total of over 20,000 employees.
In other words, this all strictly opt in --- no marketing.
There is an open source product called IMAP API which is available under 2 licenses depending on your needs: AGPL & MIT. It recently had its own Show HN [2].
