Hello
I am writing a program that sends simple text files to a remote
device.
the files have to be in the format textX.dat where X = numbers in the
range 0 up to 10 depending upon the situation. these files are stored
in a directory called attachments.
The files themselves are single line affairs in ascii.
the files have to be sent in base64.
the final email has a simple subject line, to and from addresses,
and the attachments.
so far so good, I have written the program to do this, don't laugh
here it comes.
the print statements are just there so that i can follow whats going
on at the moment.

print base
attachpath = base+'\\attachments'
if not os.path.exists(attachpath):
os.mkdir(attachpath)
# Create the enclosing (outer) message
if subject_matter == 'SU':
subjectstring = 'KKK_KRDS1_'+serial+'_SU'

outer['Subject'] = subjectstring

outer.add_header('Content-Description','Remote Management System')
outer.epilogue = ''

for fileName in fileNames:

f=open(path,"rb")
bodytext = f.read()
f.close()
ctype, encoding = mimetypes.guess_type(path)
maintype, subtype = ctype.split('/', 1)
if maintype == 'text':
msg = MIMEText(bodytext)
else:
print 'we got a problem here'
break
Encoders.encode_base64(msg)
# Set the filename parameter
filestart,extension = fileName.split('.',1)
fileName = filestart+'.dat'
msg.add_header('Content-Disposition', 'attachment',
filename=fileName)
outer.attach(msg)
# Now send the message
s = smtplib.SMTP('smtp.paradise.net.nz')
print 'connecting'
s.sendmail(fromAddr, toAddr, outer.as_string())
print 'sent email'
s.quit()
sender = email@address
copieraddr = email@address
send_dat_files('SU', '65AN88888',sender,copieraddr)

questions are:
1. you may note that i have to change the file extension to .dat,
this is a requirement of the receiving device, when i do that to the
file attachment directly, the encoding does not work. any idea why?
2. the attachment files will be generated by anothe bit of code that
i am writing, it strikes me as being a bit clunky to wirte these to an
extenal folder then copy then in to the above, is there anywhay that
i can take a string, then pretend that it is a file and attach it to
the email?
sorry if this is a bit long.
look forward to hearing from anyone
kind regards
