What is the daily email limit in Google Apps Script?

Solution
You can use `MailApp.getRemainingDailyQuota()` to get an "estimate" of how many more emails to distinct recipients you can send for the day.
I haven't sent any emails today and the function returned `500`, so that confirms the daily limit suggested by Joseph.
Problem
Can someone tell me if there is a webpage that lists the official Google limit (Quotas) on emails sent from a Google Apps Script? In testing my little script I got an error: Service invoked too many times: email (# 59) and now I can't send any more emails. The obvious place for this information would be in the MailApp.sendEmail documentation. But, that does not say anything about a limit. I found this discussion on the google forum from 2/11/10 where users discuss about a 100 or 500 emails/day limit, with a 24 hour ban, but no one from Google provided an official answer. Note that this is for Google Apps Script, which is different from the Google App Engine, which does have well published limits.
