SMTP via GMAIL

[binaryjesus]

i have a lot of experience in gmail. i use it to store 100GB's of
server backup on it.

the form: field will be equal to the gmail acc u login with.

you are not clear with ur cc: so i cant offer any help on it. but u
can include multiple addresses in the To: and use Bcc:

since python doesnt include bcc in sendmail but there is a hacky
method to do that

to ='email at email.com \n\rBcc: email2 at gmail.com'
snedmail(from,to,mail)

this hack is also known as header injection attack
