Hello,

Did you receive a error message similar to ERROR Failed to connect to mail.example.com:25 [SMTP: Failed to connect socket: Connection timed out (code: -1, response: )]

The following checklist can help with troubleshooting and finding the source of the problem :

  • Does your firewall allow outbound smtp 25/tcp ?
  • Is the name of the remote server typed correctly?
  • Are you able to reach any external mail server on port 25?
  • Was your connection blocked for abuse either at your hosting or the destination?
  • What happens when you manually telnet to the remote server on port 25?
  • Check your email for an email abuse notification from your hosting company
