Version: 3.1 Configure SMTP mailing in WordPress, including support for sending e-mail via SSL/TLS (such as GMail).
Most likely, no. Not unless you have a preference for having your mail sent out via a different SMTP server, such as GMail.
Check out the settings for your local e-mail program. More than likely that is configured to use an outgoing SMTP server. Otherwise, contact your host or someone more intimately knowledgeable about your situation.
If your settings worked, you should receive the test e-mail at the e-mail address associated with your WordPress blog user account. That e-mail contains a time-stamp which was reported to you by the plugin when the e-mail was sent. If you are trying out various setting values, be sure to record what your settings were and what the time-stamp was when sending with those settings.
There are a number of reasons you could be getting this error:Your server (or a router to which it is connected) may be blocking all outgoing SMTP traffic. Your mail server may be configured to allow SMTP connections only from certain servers. You have supplied incorrect server settings (hostname, port number, secure protocol type).
The connection to the SMTP server was successful, but the credentials you provided (username and/or password) are not correct.
