Send email
You are encouraged to solve this task according to the task description, using any language you may know.
Write a function to send an email. The function should have parameters for setting From, To and Cc addresses; the Subject, and the message text, and optionally fields for the server name and login details.
- If appropriate, explain what notifications of problems/success are given.
- Solutions using libraries or functions from the language are preferred, but failing that, external programs can be used with an explanation.
- Note how portable the solution given is between operating systems when multi-OS languages are used.
(Remember to obfuscate any sensitive data used in examples)
Python
The function returns a dict of any addresses it could not forward too. Other connections problems raise errors. Tested on Windows, it should work on POSIX platforms too.
<lang python>import smtplib
def sendemail(from_addr, to_addr_list, cc_addr_list,
subject, message,
login, password,
smtpserver='smtp.gmail.com:587'):
header = 'From: %s\n' % from_addr
header += 'To: %s\n' % ','.join(to_addr_list)
header += 'Cc: %s\n' % ','.join(cc_addr_list)
header += 'Subject: %s\n\n' % subject
message = header + message
server = smtplib.SMTP(smtpserver)
server.starttls()
server.login(login,password)
problems = server.sendmail(from_addr, to_addr_list, message)
server.quit()
return problems</lang>
Example use: <lang python>sendemail(from_addr = 'python@RC.net',
to_addr_list = ['RC@gmail.com'],
cc_addr_list = ['RC@xx.co.uk'],
subject = 'Howdy',
message = 'Howdy from a python function',
login = 'pythonuser',
password = 'XXXXX')
</lang>
