And yes I'm aware that Gmail is more properly webmail as opposed to a mail client. On a related note is there a way to have the To: field automatically filled upon opening a message composition page in gmail? I'm sure there's a much better way to do email than the way I'm doing it, but I suppose the real issue at hand for me is the fact that the third level toplevel is opening WAY too small and the title doesn't show.
I think your computer has not smtp server running but you must put in your Internet Service providers SMTP server information. From field could probably be faked, but replies would not arrive OK. Like some companies or mailing lists no_reply.... Email addresses. I try to take the code and let it transmit itself to you now that I dig up some stuff for gmail from net.
See the code snippet I posted. There was some issue with bytes trying to send the code of the program from Python3, so in snippet there is only simple built in string sent instead. Subject is left incorrectly sam as in message I sent to you. The program has the information how to use gmails SMTP, not ISP specific one.
