When clicking on the "Send an Email" button on the emails related list on cases, you get the page of the same name. On this page, there is a field to select the From address.
How can you remove some email addresses from the "From" picklist?
I understand form https://help.salesforce.com/HTViewHelpDoc?id=email_send.htm&language=en_US that the email addresses shown in the picklist are those with email2case routing. (Some email addresses are shown twice in the picklist, so I am not sure about this.) If this is true: Can you still have email2case routing for [email protected] without [email protected] showing up in the "From" picklist on the "Send an email" page? Maybe a JavaScript hack would do the trick, but I want to avoid this if possible.
