I'm having issues getting emails sent when tickets are opened. Brand new installation on a Synology Diskstation. It looks to me like it is version 1.6. I'm guessing that because it says this on my Settings Tab:

System Preferences and Settings (v1.6 ST)

None: Use PHP mail function

The email address where I want the tickets to be sent to.

What to you have Default Alert Email set to?

Use Default System Email (above)

scroll down to Alerts & Notices

What do you have enabled here?

New Ticket Alert - enabled. The rest are still disabled.

admin panel -> emails

click on your default alert email

if you are using SMTP are your settings here correct?

As far as I can tell, yes they are correct. I have tried setting the SMTP host as "localhost" and as the ip address of the server.

Is the email you are using to open a ticket the same as your default email address?

No - these are different email addresses but they are from the same domain.
