[bug-mailutils] How to find last message?

[Jean Louis]

Dear Sergey,

I have a system of Maildirs in the scheme such as
~/Maildir/address@hidden/

That is helping me quickly locate the conversation
belonging to certain email address.

There are 33281 such folders on my side.

I can easily count interactions with people by
using messages program, that helps me to sort out
who are those people who are better or well
connected with me.

However, I would like to find a an automatic way
to find out either folders or/and messages where
the last email has been sent by myself, by one of
my email addresses, or by using other type of
query.

What idea comes up in your mind if you wish to
find out if the last message within a folder have
been sent by certain email address?

I have reviewed sieve, and few programs, I do not
find it.

I am thinking in this direction: if `messages' can
find the number of messages in the inbox, I
already go that number of the last message.

And how do I access programmatically only the last
message to search for email address?
