Just a small notice, if you're ever going to send a Yii application through Gmail. Make sure, that you browse archive, that you're about to send, and delete all
*.bat files from
framework folder. If you miss that, Gmail will refuse to send email with such attachment, due to "executable file inside".
Pity is, that this error pops up after attachment is uploaded to Gmail. An archive containing full framework code can take 10 MB or more and can waste some time to attache it to Gmail.
