# Error: SMTP connect() failed

 * I’ve been a very happy user of this plugin. Unfortunately, since a short while,
   it has stopped working. Now I can’t send any messages.
 * I’ve been using the plugin to send messages via my Microsoft Outlook.com address,
   for the main purpose of receiving form responses from my own website, because
   the webserver’s php mail() function has been supressed. Now, when I try to send
   a test message, I get a lot of errors.
 * Log: (personal info omitted with <<<CONTENT>>>)

       Test Message Sent
       The result was:
       bool(false)

 * I am encountering the exact same problem. Did you resolve this? If so, then how
   did you do it?

 * Hi kcwebguy,
 * I wasn’t able to resolve it and I have little confidence that the plugin author
   will make an update anytime soon. I moved my websites to a new server and configured
   it so that I could use PHP mail() again, instead of bothering with SMTP.
 * As an alternative – and this might be interesting for you – I did initially consider
   using Mandrill. You can sign up for a small amount of mails per month for free,
   and there is a good plugin available around here as well. [https://wordpress.org/plugins/wpmandrill/](https://wordpress.org/plugins/wpmandrill/)
 * Good luck!
