Subject: [Imap-protocol] Imap Search Command Parse Logic

Hi,
|
|
|
|
|
|
|
|
I'm currently working on implementing IMAP protocol on our mail server.
|
|
This is my first time implementing such a big project and I've so far coded
|
|
a majority of IMAP commands in the RFC, except the Search command.
|
|
|
|
I've been searching on the internet and studied postfix(RPN) algorithm for
|
|
weeks to see how to parse the search command correctly.
|
|
|
|
It seems Postfix would work until I encountered something like OR OR A B C D
|
|
==> (OR (OR A B) C) D
|
|
|
|
Could anyone point me a direction on how to implement the Search command
|
|
when there are multiple ORs?
|
|
|
|
Should I even consider using Postfix(RPN) algorithm to parse search command?
|
|
|
|
|
|
|
|
Thank you very much for any help or tips you could provide.
|
