[Tutor] smtplib alternative???

[Liam Clarke-Hutchinson]

>Generally smtp servers are only configured to send to or from domains in
which they belong.

Hmmm... several ISP's I've used allow any value in the "From" header field.
I'd also like to mention that while many SMTP servers will only allow a
valid domain address in the From field, there is usually no such restriction
on what you stick in the "Reply-To" header field.

(I'd like to point out that using fake "From" addresses gets boring after
about the fifth prank email from big_Billy.G at microsoft.com to your
friends...)

The ability to change a "From" field is very useful for automated emailing.
(By which I don't mean spam, but those emails from noreply at foo.com...)

Hi Danny,

Yes, when sending an email your mail client will always send the email to
the mail server specified by the MX record in the authoritive domain.
Usually the domain specificed after the @ symbol. The problem with smtplib
is that I have to specify the mail server I'm sending email too. What if I
wanted to send an email to 3 different people on three different domains
hosted by 3 different mail servers? Smtlib prohibits this functionality. Do
you see what I mean now...?

Thanks for replying...

Hi Adisegna,

I've always assumed that emails have to talk with some SMTP server. RFC821
seems to confirm this:

     http://www.faqs.org/rfcs/rfc821.html

so what you're asking, to be able to send mail without an SMTP server, may
not be possible.  There is an 'smtpd' module that comes with Python:

     http://www.python.org/doc/lib/module-smtpd.html

I'm also not sure I understand the reason you're trying to avoid talking to
an outside smtp server.  But again, I'm unfamiliar enough with how the SMTP
email protocol really works that perhaps I'm just overlooking something.
