[StGit PATCH] mail: Ask for the SMTP credentials before sending the messages

[StGit PATCH] mail: Ask for the SMTP credentials before sending the messages

[Catalin Marinas]

The original implementation was asking for the SMTP password on every
patch sent. This patch only asks the password once before sending or
even editing the cover message and patches.

I don't have time to investigate at the moment, but "make test" fails in

The patch was converting the message headers to Header objects rather
than strings so that the long-line folding is done using "\n " rather
than "\n\t" (Outlook cannot handle the latter correctly). But it looks
like the Python library assumes that they are strings and getting
"content-type" fails (I would say Python bug).

Anyway, I change the patch so that it only converts the the Subject
header which is the one that bothers me most:

    mail: Use space rather than tab for long subject header folding

    The default Python implementation (at least 2.5 and earlier) fold long
    e-mail header lines by inserting "\n\t". This causes issues with some
    e-mail clients that remove both "\n\t". The RFC2822 shows that folding
    should be done with "\n ". The Python workaround is to use a Header
    object instead of a string when setting the message headers.
