Autor: Clive Haworth Data: Para: Exim-users Asunto: [exim] How to configure exim to run a command on SMTP error 551
(user not local)
My application sends emails via exim to members of my site. Occasionally
people move from an organisation and don't update their email address. I
need to somehow run a command if I get one of these 'bounces' to update
the status of the user in the application.
