My organization uses Mailman for managing email distribution lists. We will be sending a weekly newsletter to our large subscriber database soon. Due to the way Mailman works, the ability to relay email is based on the FROM value in the email. As you know, ZOHO only allows two types of FROM values, the admin and signed-in user. This limitation poses a problem for me because I have 10 different lists with 8 different email addresses with the relay privilege. As I cannot script a sendmail event to use one of these privileged emails, I'm stuck.

I'd like to propose that ZOHO set-up a mechanism to allow ZOHO-verified emails (ZOHO account names) to be used via script. In the following example, all these ZOHO account names are registered users in my organization.
