Ricardo -
I say this in the nicest way possible, but did you RTFM? :)
Python has built-in help support on modules.
You should start there, do some Googling, and if you're stumped, get
some help. Not for any other reason than it'll probably get you 1) more
experience at navigating the docs, and 2) a quicker, probably more
detailed response.
So using Help, we get:
>>> import smtplib
>>> help(smtplib)
Help on module smtplib:
NAME
smtplib - SMTP/ESMTP client class.
FILE
c:\python24\lib\smtplib.py
[snip 10 pages of documentation]
>>> help(smtplib.SMTP.set_debuglevel)
Help on method set_debuglevel in module smtplib:
set_debuglevel(self, debuglevel) unbound smtplib.SMTP method
Set the debug output level.
A non-false value results in debug messages for connection and for all
messages sent to and received from the server.
>>> help(smtplib.SMTP.ehlo)
Help on method ehlo in module smtplib:
ehlo(self, name='') unbound smtplib.SMTP method
SMTP 'ehlo' command.
Hostname to send for this command defaults to the FQDN of the local
host.
>>> help(smtplib.SMTP.sendmail)
Help on method sendmail in module smtplib:
sendmail(self, from_addr, to_addrs, msg, mail_options=[],
rcpt_options=[]) unbound smtplib.SMTP method
This command performs an entire mail transaction.
The arguments are:
- from_addr : The address sending this mail.
- to_addrs : A list of addresses to send this mail to. A bare
string will be treated as a list with 1 address.
- msg : The message to send.
- mail_options : List of ESMTP options (such as 8bitmime) for the
mail command.
- rcpt_options : List of ESMTP options (such as DSN commands) for
all the rcpt commands.
If there has been no previous EHLO or HELO command this session, this
method tries ESMTP EHLO first. If the server does ESMTP, message size
and each of the specified options will be passed to it. If EHLO
fails, HELO will be tried and ESMTP options suppressed.
This method will return normally if the mail is accepted for at least
one recipient. It returns a dictionary, with one entry for each
recipient that was refused. Each entry contains a tuple of the SMTP
error code and the accompanying error message sent by the server.
This method may raise the following exceptions:
SMTPHeloError The server didn't reply properly to
the helo greeting.
SMTPRecipientsRefused The server rejected ALL recipients
(no mail was sent).
SMTPSenderRefused The server didn't accept the from_addr.
SMTPDataError The server replied with an unexpected
error code (other than a refusal of
a recipient).
Note: the connection will be open even after an exception is raised.
Example:
>>> import smtplib
>>> s=smtplib.SMTP("localhost")
>>>
tolist=["[EMAIL PROTECTED]","[EMAIL PROTECTED]","[EMAIL PROTECTED]","[EMAIL
PROTECTED]"]
>>> msg = '''\
... From: [EMAIL PROTECTED]
... Subject: testin'...
...
... This is a test '''
>>> s.sendmail("[EMAIL PROTECTED]",tolist,msg)
{ "[EMAIL PROTECTED]" : ( 550 ,"User unknown" ) }
>>> s.quit()
In the above example, the message was accepted for delivery to three
of the four addresses, and one was rejected, with the error code
550. If all addresses are accepted, then the method will return an
empty dictionary.
>>>
So mess around in the built-in docs, then check python.org's docs, and
let us know what you find :)
Also, try experimenting! pass it stuff that you don't think will work
just to see if maybe it does :D
