## Changes

### 2024 May 29

* First change is changing the name to match what I have on the server.
* Second change is to have the `#!` path hopefully pointing in the right place.
* Which I screwed up.  I think I was typing in the wrong window.
  * It's not failing on command line.
* Still failing, let's get some logging.
  * Moved logging initialization, and included print statements.
  * OK, it's logging now (it may have been but not in the right location)
  * It wasn't formatting correctly.
* Testing different way to handle formatting.
  * Nope used `Format` not `Formater`.
  * This is not working
* Reverting to previous formatting
* No idea what steps we've gone through to get here.
* Let's try again.
* OK, basicSettings all set at once.
  * This sorts it, now let's get a date format working
* Now let's see if this works...
  * Date format set:
  * Level and File set in variable
  * Format had errors with `$` used instead of `%`
* Clean up logging to not log what was logged for logging diagnostics.
* Logging host and port on same line.
* OK, parsing port number, and setting default.
* Logging error (I hope), when lmtp fails to be created.
  * Maybe this is better?  
  * Catch exception, log based on that?
  * Hm, go with bare "Exception"...  The catch wasn't what was failing.
  * Let's try that instead?
* Oh man...  Variable not properly defined (or more derferenced.)
* OK, it's failing further along, so maybe this works?
* I see...  
  * The parsing of the environment variables is failing, but let's try this.
* That's not doing it...  Might need to create users?
* OK, let's see if what I need is in the headers...
* Using the "To" header...  Let's see if that gets us anywhere.
* It's not finding it.
* Oh man `To` vs `'To'`
* Progress...  But getting, "line too long" this seems like I need the 
  replace that I had before.
