[Dovecot] How to rewrite header from X-Original-To to Delivered-To

[Kiran Reddy]

Hi,

If mail headers contains 2 lines Delivered-To and 1 X-Original-To. I 
want to keep first line of Delivered-To and X-Original-To and delete 2nd 
line of Delivered-To and rewrite X-Original-To to Delivered-To.

Please find the mail headers as below.

X-Original-To: 98862xxx65 at example.in  ====> Rewrite this to Delivered-TO
Delivered-To: mobilemail at example.in    ====> KEEP This Header
Delivered-To: example.com-mobilenumbers at example.com =======> Delete This 
Header


Return-Path: <syed.s at example.com>
X-Original-To: 98862xxx65 at example.in  ====> Rewrite this to Delivered-TO
Delivered-To: mobilemail at example.in    ====> KEEP This Header
