Dear, and how in General should be organized to send emails from the site? This refers to the standard designs, where the letters are required to confirm your user registration, expulsion of a forgotten password, etc. Need to raise for hosting sendmail/postfix/exim and send through it or you can use hmelovsky smtp (because there is a limit on the number of outgoing messages) or something else? What is now the most kosher way? You have this question in your projects decide?
