 # generic SMTP emailing function in Python, using SSL
 # will take values from these env params: 
 # EMAIL_SERVER : SMTP server url
 # EMAIL_PORT : SMTP port num (must be the SSL port)
 # EMAIL_SENDER : Email account whose SMTP login you're using
 # EMAIL_PW : SMTP password of the email account (likely same as regular password used to login to that account)
 # tested and works well with BigRock.in hosting account's email accounts.
 # ..and with Google workspace account IF you enable "allow less secure apps".
