Update to Bitrix24 email client via source code - Private Mo

We now have a Bitrix setup on a development server to play with, see logins and FTP access below.

What we are looking to achieve is:

1) Not mark email as read on open (via source code).

2) Email search update - improve the search criteria (via source code).

For example, currently it works like this:
For the subject [Crystal Order Sign Off - 330359 - ORD40305]
A) If [40305] is searched, there will be no result.
B) However, if [ORD4], [ORD40], [ORD403], or [ORD4030] are searched, there will be a result.
We want there to be a result with point A

You have estimated a time to complete of 2 weeks and the budget has been agreed as at £350

Thanks
Chris.
