Reading the above thread, I see that it has a variety of opinions. Having had my account banned from e-mail (or maybe I was on server 37?), I contacted customer support with the same question. The answer I got was 5 e-mails in an hour or 30 e-mails in a day. Which of the following is true:
1. Has the e-mail sending limit changed to 30 e-mails in 5 minutes or 100 e-mails in an hour?, or
2. Was the customer support wrong?, or
3. Is the thread above wrong?
Furthermore, is there a place to check how much e-mails had been sent already? I have a site where people can send something along the lines of greeting cards to each other. At this point, I had been able to track down a problem when the greeting cards contain non-latin letters. In an attempt to fix the problem, I would need to try applying various patches, and after each one e-mailing myself to see whether the problem is resolved. Doing so, I would not want to exceed the limit, all the while keeping in mind that people might send a greeting card to each other while I am doing this. So if there is a place to check how much e-mails had been sent already, I would be able to make a script that would postpone the sending of an e-mail if this limit is exceeded.
