mailHost is the name of the mail server server you are sending the
email to/via, for internet mail this will be a server from the
recipient's domain's mx records (or your ISP server).
reply_email is the full email address of the sender, or the email
address you wish to appear as the sender. It does not have to be the
same address as used in the body headers
email is a bad choice for a variable name, try something like
to_email, in your case it should contain the full email address of
the recipeint or a list of recipients. The address(es) do not have
to be the same address as used in the body headers
server.sendmail returns a list of failed recipient email addresses if
only some failed, if all the recipients failed you get an exception.
Apologies for the bad formatting below, its untested but should show
you the structure for managing an SMTP msg send. You could tidy it up
without too much effort
import sys
for mailHost in MX_records:
try:
print "Sending message to host: %s" % mailHost
server=smtplib.SMTP(mailHost)
failed = server.sendmail(reply_email,email,body)
server.quit()
break
except smtplib.SMTPRecipientsRefused, x : #all recips failed
for recip in x.recipients:
print recip
server.quit()
break
except smtplib.SMTPDataError, x: # an error at the end of the
# message body = MSG Failed
# all recips failed
print x[0], x[1]
server.quit()
break
except smtplib.SMTPSenderRefused, x : # the sender was refused = #MSG failed
# all recips failed
print x[0], x[1]
server.quit()
break
except: #can't connect so continue to next MX server - don't fail !!!
e_error = str(sys.exc_info()[0])
print e_error
server.quit()
continue
for recip in failed: # some failed, some didn't
print recip
