As is the case of adding or removing email addresses on an email list via an email message to the server, can you add Subscriber Field data the same way?
Example: I would like to add jsmith@abc.com to the email list "members@somedomain.com". So I would send an email to STServ@somedomain.com with the command "subscribe".
Can I include the person's name that is subscribing in the Subscriber Field that I have set up?
