Hi all,
I am playing with the smtp and email modules from the standard library
of Python 2.7.3 (I also want it to run on 2.6.6). I've not found the
going easy; the SMTP and RFC 2822 standards are not ones I have worked
with before. I have something that works, but I am not confident I am
doing the right thing. For that matter, I am not very confident that I
am not doing the wrong thing.
I would very much appreciate some more experienced eyes on the code below.
In addition to any outright errors concerning interaction with an SMTP
server and constructing a MIME message, I would of course also welcome
style comments. (Preemptively, I will note it isn't obvious I ought to
have gone OOP with this.)
I should also mention that I am writing this code as part of some
tools to send myself and others reminder emails, the tools to be run
from a cron job. I am storing an actual email account password in
plaintext in my code. But, the account in question is one established
just for the purpose of the reminder project and similar projects; it
is not an account which houses my plans for world domination or the
like. That said, I have removed the account name and password string
below; it will thus require some adjustments to run for testing.
And, as I side note, could anyone explain why changing a first world
of a body line 'From' to '>From' is the preferred standard? I
understand what the problem is that is being solved, but as most email
clients interpret a leading '>' as an indication of quoting, I would
have thought ' From' or something like '-From' would have been better.
If I have my own code deal with the problem in one of these ways, will
I be breaking anything?
Anyway, thanks and best,
Brian vdB
