Send email
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.
You are encouraged to solve this task according to the task description, using any language you may know.
(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>
