Send Confirmation Email from Email Address other than zoho.adminuserid

Send Confirmation Email from Email Address other than zoho.adminuserid

Can anyone recommend a deluge approach (or 3rd party plugin approach) to allow for sending from any outside email address (smtp, etc...) other than from deluge defaults of zoho.adminuserid and zoho.loginuserid ???

Surely there is a method to call email functionality from outside zoho?
