I Got 'Could not connect to mail server' Error Sent via WebMail
You tried to send a message via WebMail but you got the error
These are 3 possible causes:
1. You have incorrectly configured your Outgoing Mail Server
To check for this error, log onto WebMail with an admin level account and go to Settings - Administrator Settings
Check you settings for Outgoing Mail Server. By default this is set to localhost, which assumes your Webmail Server is running on the same machine as your Merak Email Server. If you are running Webmail on a different server or you are using IP binding for domains then you should updat e this setting with the IP address to match your installation.
2. Your SMTP Service is stopped
The SMTP service must be running for Webmail to work correctly. This can be checked, and started in System -> Services in the Merak Administration Console.
3. The SMTP port is blocked
Check you Firewall and Router configurations to ensure that your SMTP port is not blocked in any way.
The default port for SMTP is 25 but you may have changed it in your installation.
