Remove "Duplicate" emails

[@lbutlr]

OK, perhaps I tried to cover too much, so let's just look at this:

If I run this command, I get no errors:

doveadm expunge -u kremels MAILBOX-GUID 1488800748.47633_1.mail.covisp.net UID 22908

But, if I search again 

doveadm -f table fetch -u kremels 'hdr.message-id guid uid hdr.x-listname' mailbox 'Archive' | sort| awk 'cnt[$1]++{if (cnt[$1]==2) print prev[$1]; print} {prev[$1]=$0}' |grep -E "[0-9]  +$" |awk '{print "doveadm expunge -u kremels MAILBOX-GUID "$2" UID "$3}' | grep 22908
hdr.message-id             guid                uid hdr.x-listname
doveadm expunge -u kremels MAILBOX-GUID 1488800748.47633_1.mail.covisp.net UID 22908

The message is still listed.

Am i misunderstanding something about how expunge works or what it does?

How do i remove the messages in such a way that they will not show up in subsequent searches (as far as I can tell, assuming the 1488800748.47633_1 is the first part of the file name in the maildir, the message is actually deleted).

 $ find Maildir -name "1488800*"
Maildir/.Archive/cur/1488800350.46962_1.mail.covisp.net:2,S
Maildir/.Archive/cur/1488800633.47337_1.mail.covisp.net:2,S
Maildir/.Sent/cur/1488800118.M2833P43167.mail.covisp.net,S=1221,W=1251:2,Sad
