This code works and sends me an email just fine:

import smtplib 

#SERVER = "localhost" 

FROM = '[email protected]

TO = ["[email protected]"] # must be a list 

SUBJECT = "Hello!" 

TEXT = "This message was sent with Python's smtplib." 

# Prepare actual message 

message = """\ 

From: %s 

To: %s 

Subject: %s 

%s 

""" % (FROM, ", ".join(TO), SUBJECT, TEXT) 

# Send the mail 

server = smtplib.SMTP('myserver') 

server.sendmail(FROM, TO, message) 

server.quit()

However if I try to wrap it in a function like this:

def sendMail(FROM,TO,SUBJECT,TEXT,SERVER): 

import smtplib 

"""this is some test documentation in the function"""

 message = """\ 

From: %s 

To: %s 

Subject: %s 

%s 

""" % (FROM, ", ".join(TO), SUBJECT, TEXT) 

# Send the mail 

server = smtplib.SMTP(SERVER) 

server.sendmail(FROM, TO, message) 

server.quit()

and call it I get the following errors:

Traceback (most recent call last): 

File "C:/Python31/mailtest1.py", line 8, in <module> sendmail.sendMail(sender,recipients,subject,body,server) 

File "C:/Python31\sendmail.py", line 13, in sendMail server.sendmail(FROM, TO, message) 

File "C:\Python31\lib\smtplib.py", line 720, in sendmail self.rset() 

File "C:\Python31\lib\smtplib.py", line 444, in rset return self.docmd("rset") 

File "C:\Python31\lib\smtplib.py", line 368, in docmd return self.getreply() 

File "C:\Python31\lib\smtplib.py", line 345, in getreply 

raise SMTPServerDisconnected("Connection unexpectedly closed") smtplib.SMTPServerDisconnected: Connection unexpectedly closed

Can anyone help me understand why?

To send email in Python you can use the below-mentioned code:-

import textwrap 

def sendMail(FROM,TO,SUBJECT,TEXT,SERVER): 

import smtplib 

"""this is some test documentation in the function""" message = textwrap.dedent("""\ 

From: %s 

To: %s 

Subject: %s 

%s 

""" % (FROM, ", ".join(TO), SUBJECT, TEXT)) 

# Send the mail 

server = smtplib.SMTP(SERVER) 

server.sendmail(FROM, TO, message) 

server.quit()
