Hi there,
I want to send an email with an attachment using the following code (running
under Python 3.1, greatly simplified to show example)
from email.mime.multipart import MIMEMultipart
from email.mime.text import MIMEText
msg = MIMEMultipart()
msg['From'] = from_addr
msg['To'] = to_addr
msg['Subject'] = subject
msg.attach(MIMEText(body))
fp = open(att_file)
att_msg = MIMEText(fp.read())
attachment = att_msg.add_header('Content-Disposition', 'attachment',
filename=att_file)
msg.attach(attachment)
# set string to be sent as 3rd parameter to smptlib.SMTP.sendmail()
send_string = msg.as_string()
The attachment object msg1 returns 'email.mime.text.MIMEText' object at
<address>', but when the att_msg.add_header(...) line runs the result is
None, hence the program falls-over in msg.as_string() because no part of the
attachment can have a None value. (Traceback shows "'NoneType' object has
no attribute 'get_content_maintype'" in line 118 of _dispatch in
generator.py, many levels down from msg.as_string())
Has anyone any idea what the cause of the problem might be? Any help would
be appreciated.
.add_header() modifies the MIMEText object *in-place*; per Python
conventions, mutator methods return None; hence, attachment = None.
Try instead (untested):
att_msg.add_header('Content-Disposition', 'attachment', filename=att_file)
msg.attach(att_msg)
Cheers,
Chris

Hi Chris,
You are right - that does the trick.
Many thanks,
