You need to evaluate the content of your email before sending it. The Outgoing servers of Hotmail are using the spam evolution software which scans and tracks the content of the email. The spam scanner set at the most lenient level will prevent the emails which have a high spam score. It will evaluate both the title and the body of the email. Don’t use popular spamming terms like a prize, lottery, etc. Rewrite the message of the body, if there is any suspicious term and then try to send it again.

If this problem persists then the Internet Service Provider is blocking port 25 of the Outgoing mail server. You can use the email server instead of using your own. You can also switch the port 587 if you don’t want to use your ISP’s server for SMTP.
