I use git-send-email and msmtp combination.
I also use mutt and msmtp combination.
Could you provide me quilt mail and git-send-email configuration?

Sometimes when a developer sends his patch. He receives a reply this
patch has been already submitted by another developer.

I think the reason is that when a developer starts working on a patch,
he has not bleeding edge copy of maintainers tree. There is a long
review cycle of patch which is required for a large project as Linux.

So, I have a solution. As patches are collected on patchwork.kernel.org.
While patches are under review, it can be tracked by a bot and show lines
of code,on a web page, which will be affected on the basis of currently
submitted patch. So, developers don't touch those lines of code.
I also propose in-queue branch(patches in queue to be applied) for maintainers, 
which will help a maintainer to know which patches has been selected by
other maintainer. I think there will be less conflicts.

If you help me answering few questions as I develop this system, I will
be grateful to you.
