git send-email does not work with Google anymore?!

[Lars Schneider <larsxschneider@xxxxxxxxx>]

Hi,

I used to use the Google SMTP server to send my patches to the list with 
the following config:

    [sendemail]
        smtpencryption = tls
        smtpserver = smtp.gmail.com
        smtpuser = larsxschneider@xxxxxxxxx
        smtpserverport = 587
        from = larsxschneider@xxxxxxxxx
        chainreplyto = false
        suppresscc = self

Apparently that stopped working today. I get this error:

    (mbox) Adding cc: Lars Schneider <larsxschneider@xxxxxxxxx> from line 'From: Lars Schneider <larsxschneider@xxxxxxxxx>'
    Password for 'smtp://larsxschneider@xxxxxxxxx@smtp.gmail.com:587':

Of couse I tried to log in via web browser etc. Does anyone else use 
Google as SMTP server? If yes, does it work for you?

Thanks,
Lars
