Autoresponders
1) An autoresponder cannot have the same name of a POP account. If you would like to create an autoresponder for a POP account, read the following.

   Scenerio: You want a sales email account to send an autoresponse everytime someone sends mail to it.
First, create an email account such as "sales3".
Next create the autoresponder "sales".
Last, within your redirect, point "sales" to "sales3".
When the user sends mail to "sales@yourdomainname.org", they will recieve the autoresponse, and "sales3" will recieve their email.
