It happens very often that I have multiple copies of the same email in the
same folder. The most frequent reason is that one copy ist sent directly to
me and another one (or more) by forward from other recipients. Another reason can be that the email has manually been saved in a folder more than once
(then all other copies should be in "deleted" state but sometimes deleted emails are ressurected for various reasons).

Whatever the reason, Iod like to know a simple way to discover that several emails in the same folder have the same Msg-Id, and then to delete all but
one of them, preferably keeping the shortest one (= the one with the fewest forwards). I do not want the deletion to be fully automatic because there are situations where I want to see which copies have reached me.

My current solution is to search for the "Return-Path"-Header that
appears most often in duplicated emails. This covers many cases but is
a bit clumsy.

Not in Alpine but Thunderbird has an addon that finds duplicate emails.

Simple but clumsy (you have to know the Message-ID: of each message ando
do it manually ... maybe it helps if you preliminary sort the folder by subject (command $ O)

Then read part of the Message-ID: string ... e.g. 9116073

Then search with commands ; T H Message-ID: 9116073

; = search
T = by text
H = by header kwd
Message-ID: is the kwd name
9116073 or whatever is the partial stering to be matched
