Developing web, want to disable sendmail...

[dudinatrix]

I'm developing an ecommerce site on my local Ubuntu system with some data carried over from our live setup (customers/orders/etc.) -- Problem is, when I do some testing during development, Ubuntu sends out emails (ie, "Your order has been shipped") and I want to avoid this to prevent actual customers from receiving anything.

How can I disable sendmail, and turn it back on later?

You should just be able to sudo /etc/init.d/sendmail stop
