If you just want to send mail, you should be able to use the standard smtplib module (http://docs.python.org/lib/module-smtplib.html). If your recipients are on the Internet, you would need to handle MX resolution yourself.
I know you said you want to avoid a relay server, but it's probably the best bet unless you control the SMTP infrastructure or are simply sending messages locally. Otherwise, you'll probably need to also implement queuing and retry logic (depending on your requirements). There are also some warning lights that may go off and flag your mail as spam if you're using a method like that... -Jeff On 7/5/07, _spitFIRE <[EMAIL PROTECTED]> wrote: > Is it possible to run a SMTP server that sends mail to recipients > using standard libraries, without using twisted framework, and also > without using any relay server? > > -- > http://mail.python.org/mailman/listinfo/python-list > -- http://mail.python.org/mailman/listinfo/python-list
