[Dovecot] How Can I Add New Flags

[Sezai KARATOZ]

I know it that is bad choice. But we have use Courier imap for 5 years. It
is so stable and giving no problem to us. I want to use Dovecot partially in
our system. Because in any problem, we must reply so much customer email :)
So It is better to use together them until adapt Dovecot to us.

Thanks,
Sezai
