[imp] Replies are sent to wrong email ids

[ANANT S ATHAVALE]

Dear List,

I observed the following while using HGWE 5.1.1.

I have configured IMP backends.php with option for cache as 'cache'.  I
have Cyrus IMAP setup.

1. Open a mail.
2. Delete the mail.
3. Next mail gets opened.
4. I click on Reply,

In this scenario, it should open a compose message with Reply to having
addresses contained in the present mail, instead, it opens with the
previous mail which I have deleted.

Is it because of wrong caching?  It is always reproducible in my setup. 
I am using Basic View.

Please share your views.
