In development, we need a SMTP Server to see the results of send mail via SMTP protocol in Python application. Instead of configure a mail daemon, we could use this little script to receive the SMTP request, and save each session into an EML file. *.eml could be viewed with your favorite email client, you need not send them out.
Update: Fix bug for overwrite files when received multi-message in one SMTP session.

I'm so happy to learn that it's helpful to you:)
Note: This sinppet has been fixed for bug overwriting files when received multi-messages in on session.
This snippet requires running it from root account. You have to add some code to bind to a port number over 1024. Like in line 17 and 18:
and later in line 26 and later:
Of course, you have to import sys at the top of the module too.
very useful, thanks for sharing this snippet
Line 12 should be: f.close()
instead of writing an .eml you can directly send your mail to the built in python mail server. on a shell do:
then send your mails to localhost:25 and you will see the results immediately :-)
thank you man, this is awesome!! helps so much!
I'm still using this after years.
