Is sendmail is able to do the following: Forward many user emails to office 365:- [email protected] -> [email protected] [email protected] -> [email protected] [email protected] -> [email protected] [email protected] -> [email protected] Forward the following to a separate server to run php scripts:- [email protected] [email protected] An autoresponder will be sent to the sender. Does anyone know of any sample configuration I could get this started on? Is there a good autoresponder for sendmail? Our emails are hosted on Office365 and it does not allow us to run scripts. Therefore I was considering this option. Is this viable? Please refer to the diagram for more information. Thank you.
