As Will pointed out in his email, you're overthinking this.

However, I think his suggestion that you connect to port 25 is a poor 
choice. The problem here is that this assumes that the server will always 
answer and be able to process the SMTP request.

That's a bad assumption. You could check the SMTP request status and 
retry, or you could make your life a lot easier, and use the sendmail 
binary. This isn't Sendmail specific since basically every mail server 
provides the same implementation of a binary called "sendmail".

Usually, this will be implemented as something that just writes a file to 
the server's mail queue, without relying on the server actually running. 
The server will pick it up when it runs, and will handle it from there.

TL;DR - Use Email::Sender::Transport::Sendmail unless you have a really 
good reason to use something else.
