Question

I am trying to send HTML rich email, so far the code is working but the colour formatting i had in html message content is not showing when I check in my mailbox i sent to.

So far here is the code :

from email.MIMEMultipart import MIMEMultipart
from email.MIMEBase import MIMEBase
from email.MIMEText import MIMEText
from email.Utils import COMMASPACE, formatdate
from email import Encoders
import smtplib

class EMail(object):
        """ Class defines method to send email of attachment
        """
        def __init__(self, sendto, mailFrom, server, usrname, password, files, debug=False, subjt=None):
                self.debug = debug
                self.mailto = sendto
                self.mailFrom = mailFrom
                self.smtpserver = server
                self.EMAIL_PORT = 587
                self.usrname = usrname
                self.password = password
                self.subject = subjt

                # self.send(files)

        def sendMessage(self, msgContent, files):

                #collect info and prepare email
                if files:
                    if self.subject == "":
                        #Subject should contains of file attached
                        if len(files) <=3: subjAdd = ','.join(files)
                        if len(files) > 3: subjAdd = ','.join(files[:3]) + '...'
                        self.subject= self.systemLogin() +" sent mail from maya "+ os.path.basename(subjAdd)
                print "subject: ", self.subject
                msg = self.prepareMail(self.mailFrom, self.mailto, self.subject, msgContent, files)

                # connect to server and send email
                server=smtplib.SMTP(self.smtpserver, port=self.EMAIL_PORT)
                server.ehlo()
                server.starttls()#use encrypted SSL mode
                server.ehlo() # to make starttls work
                server.login(self.usrname, self.password)
                server.set_debuglevel(self.debug)
                try:
                        failed = server.sendmail(From, to, msg.as_string())
                except Exception as er:
                        print er
                finally:
                        server.quit()

        def prepareMail(self, From, to, subject, msgHTML, attachments):
                msg = MIMEMultipart()
                msg['From'] = From
                msg['To'] = to
                msg['Date'] = formatdate(localtime=True)
                msg['Subject'] = subject

                #The Body message
                msg.attach(MIMEText(msgHTML, 'html'))
                msg.attach(MIMEText("Sent from maya by Mini Me"))
                if attachments:
                    for phile in attachments:
                            #we could check for MIMETypes here
                            part = MIMEBase('application',"octet-stream")
                            part.set_payload(open(phile, "rb").read())
                            Encoders.encode_base64(part)
                            part.add_header('Content-Disposition', 'attachment; filename="%s"' % os.path.basename(phile))
                            msg.attach(part)
                return msg

and here is the HTML formatted text I am sending, (I have removed the HTML head section it being long due to css)

<body class="body_foreground body_background" style="font-size: normal;" >
<pre>

</pre>
</body>

</html>

it seems only pre tag formatting is working not the css .. why would that be ?

Was it helpful?

Solution

Gmail doesn't support <style> blocks. You can see a css support comparison between popular mail clients here: Guide to CSS support in email.
