Hello,
Believe me that I'm really interested in your project and it's not only a word for putting in my bid.
I'm an experienced Linux/Unix administrator and have worked with different email systems like Postfix, Qmail, Zimbra and more.
So I'm ready and eager to work on your project in order to back up your Zibmbra data to Google Drive.
It would be very appreciated if you give me a chance to work on this job.
