I\'m familiar with how to send emails via Google Apps Script (http://code.google.com/googleapps/appsscript/articles/sending_emails.html). It\'s super cool. But is there a way I
My gadget/script [1] does precisely that, you can reply to many emails at once from within your GMail account.
Basically I just used the Publish / Deploy as web app command (from the script editor) and in there set the options
Execute the app as: User accessing the web app
Who has access to the app: Anyone
Users then will be asked to authorise the script the first time they access it and they will run it from their own Google account, accessing their own Gmail.

Try this
var alias=GmailApp.getAliases();//This gets array of Aliases set up in gmail.
GmailApp.sendEmail(email , "Subj.. ", "body....", {from: alias[0]}); //Uses first alias
The only way to achieve that is by logging with the account of desired email, in your case "event@domain.com" and run the script with it. If you're running the script automatically via a trigger, just set the trigger with this account. If you do not have an account for it, you'd have to create one.
Adjusting the from field is not possible. There's an open issue about this on Apps Script tracker: Issue 172: Ability to send email from users different accounts ("from:" field in gmail)
--update: as one can see by following the link above, this is now possible if the desired address is an alias in your gmail.
