Question Sometimes the site reports an error like this when trying to send a message:

503 RCPT first (#5.5.1)

Answer If you are receiving this message, it means that the mail server you have configured the application to use will not accept an outbound email from your site. The application does not directly transmit the outgoing email itself. It uses the configured Email Component along with the outgoing email server you have configured the application to use. You must always have a valid outgoing email server in order to deliver email messages to the recipients. If the outgoing email server that you are trying to use is not configured correctly, or is not configured to allow you to forward your messages through it from your web server, then the messages that the application is trying to send will not be able to reach their intended destination. So, first make sure you are using the correct mail server. You should not assume that it would be the same email server that your ISP or web host may have you use for your email reader (like Microsoft Outlook or Mozilla Thunderbird). Contact your ISP or web host and ask them what mail server address you should use in order to forward outbound messages from your web server.
