There are some clear advantages of running your own email server
regarding surveillance and overall control.
If you have your own email server, you can decide of your logging
policy; and not necessarily keep a trace of all your exchanges.
You can encrypt the server hard drives. For many server seizures
this will prevent the data to be accessed right away.
You are free to decide about your backup policy. When you click
"delete", how do you know if there's not a copy that will stay
available for a year?
With Postfix and probably other mail servers, you can configure a
per server TLS policy. You can make sure that the communication with
SMTP servers used by your peers is properly encrypted (and not MITM'ed).
It makes interception a lot harder.
And you can be sure that what you receive in your mailbox will not be
harvested for data collection. Unfortunately, you are never alone: this
also depends on the server used to send the email...
