I have 1 working Splunk box with SMTP. It is SSL Bound ( I did not set this box up). I have 1 more Splunk Box that isn't SSL bound and the SMTP isn't working ( I set this one up). When I try to send a email from a dashboard perhaps. Upon sending the test email it states:
Sending the test email failed: command="sendemail", Connection unexpectedly closed while sending mail to: someone@johndoe.com
I understand this very well maybe an issue with my environment either accepting on not accepting connections coming from a http vs https. I have the exact same SMTP server information in both servers. GUI > Settings > System Settings > Email Settings. I placed the host a name of the smtp vip (there's many smtp servers behind it). for example SMTP.Whatever.com
It works for the original box, but no luck on the new box. I'm unsure of where to go from here as I have found many people with this issue. I don't know enough about Splunk to understand what the source of the problem is? Is it Splunk not happy or the SMTP server? If so I wonder what I have to do to mitigate....
Thank you
