Hi everyone,
 

Hi Tim,
I'm a newb, first time posting, so please take any of the following 
advice at face value....

# Collect form information
form = cgi.FieldStorage()
requestername = form["requestername"].value
fromaddr = form["email"].value
itemname = form["itemname"].value
description = form["description"].value
buildings = form.getlist("building")
room = form["room"].value
dateneeded = form["dateneeded"].value
po = form["po"].value
budgetcode = form["budgetcode"].value
attachment = form["attachment"].value
 

based on this cookbook recipe 
http://aspn.activestate.com/ASPN/Cookbook/Python/Recipe/273844, it looks 
like cgi.FieldStorage() returns a file-like object for file input 
fields, having  .filename and .file attributes. the file attribute has a 
read() method which may be useful. having never used cgi I'm not sure 
what .value returns for file input fields, don't know if this is of any 
consequence.

buildinglist = ", ".join(buildings)
**[ misc code snipped ]**
# Set some email headers
#msg = MIMEText(msgtext)
msg = MIMEMultipart()
msg['Subject'] = itemname
msg['From'] = "%s <%s>" % (requestername, fromaddr)
msg['To'] = toaddr
if len(buildings) != 0:
   for building in buildings:
       msg['X-HRT-Building'] = building
if po != "": msg['X-HRT-PO'] = po
if dateneeded != "":
   try:
       duedate = time.asctime(time.strptime(dateneeded, "%m/%d/%Y"))
       msg['X-HRT-Due-Date'] = duedate
   except ValueError:
       pass
msg.preamble = "Tech order request"
msg.epilogue = ""
 

if you know that the attachment will always be a text file and your 
assignment of 'attachment' looks like this:

   attachment = form["attachment"]
then you might try the following (untested):
   part = MIMEText(attachment.file.read())
   # if I understand correctly, the 'Content-Disposition' header is 
necessary to make the file
   # appear in the message as an attachment, otherwise it may occupy 
the msg body.
   part.add_header('Content-Disposition', 'attachment', 
filename=attachment.filename)
   msg.attach(part)

# Send the message
server = smtplib.SMTP('localhost')
server.sendmail(fromaddr, toaddr, msg.as_string(0))
server.quit()
 

there's a great example in the email module docs if you're dealing with 
more than just text files :
http://docs.python.org/lib/node578.html (3rd example, using the 
mimetypes module)

I have collected code snippets from various sources (python docs, ASPNs 
python cookbook) into a basic MIMEMailer class, that I use fairly 
regularly in hobby projects. If anyone is interested, I'd be happy to 
share, or post it here.

HTH,
Marty
