Simple Python script as SMTP server for outgoing e-mails?

0 votes
86 views

Every once in a while, my ISP's SMTP server refuses to send perfectly legit e-mails because it considers them as SPAM.

So I'd like to install a dead-simple SMTP server on my XP computer just to act as SMTP backup server. All I'd need is to change the SMTP address in my e-mail client, and off they go. No need for anything else like user authentication or SPAM control.

Is there a no-brainer, ready-to-use solution in Python that I could use for this?

Many ISPs now block "pass through" SMTP -- especially original port 25 SMTP; only "their" server is permitted to connect to outside hosts.

If all your destinations are using TLS with alternate ports, you might be okay, but if the mail is being sent over port 25, it won't go anywhere.

WinXP Pro supposedly contains an SMTP server as part of the "Internet Information Services" (IIS6) suite (optional component activated via control panel). Win7 Pro seems to have removed that (SMTP) component from IIS7.

Rather than write something from scratch, I'd look at deploying something out-of-the-box - Postfix, for instance - which you will be able to configure much faster than writing your own. And then you could have it either send via your ISP or send directly to the receiving MTA, without much extra effort.

I have to write a small SMTP-Relay script (+ some statistic infos) and I'm wondering, if this can be done in python (in terms of performance, of course not in terms of possibility ;) ).

It has to handle around 2000 mails per hour for at least 8hours a day (which does not mean, that it is allowed not to respond the rest of the day.

Can this be done? or should I better use some other programming language? My second choice would be erlang.

I'm trying to write a python script that writes some content to a file root through sudo, but it's not working at all. I am using:

 channel = 'stable'
 config_file = '/opt/ldg/etc/channel.conf'
 command = ['echo', '-n', channel, '|', 'sudo', 'tee', config_file]
 p = subprocess.Popen(command, stdout=subprocess.PIPE, stderr=subprocess.PIPE)
 out, _ = p.communicate()

But it seems as if this isn't doing anything.

I just want to write the contents of the variable channel to the file /opt/ldg/etc/channel.conf. But whatever I try just doesn't work. Can anyone offer any pointers?

We have few rules (changeable) are stored in a database, and I need to display them for the end user in the form of flow-chart.

Is there such thing for Python?
