Arkadaşlar çokça işimi gören bir kod bloğudur. SMTP Server yani sunucu kontrolü yapabildiğiniz ve mail atmaya yarayan bir kod bloğu. Github da faydalandığım yer : https://gist.github.com/hbasria/51e5f8235e42b00f449eaba0ac4ba7c6 şeklindedir. Projenize göre kullanmanız dileğiyle 🙂

"""smtptest.py: command-line smtp test mail sender
https://github.com/turbodog/python-smtp-mail-sending-tester
Usage: python smtptest.py [options] fromaddress toaddress serveraddress 
Examples:
	python smtptest.py bob@example.com mary@example.com mail.example.com
	python smtptest.py --debuglevel 1 --usetls -u bob -p xyzzy "Bob <bob@example.com>" mary@example.com mail.example.com
At verbose == False and debuglevel == 0, smtptest will either succeed silently or print an error. Setting verbose or a debuglevel to 1 will generate intermediate output.
