This used to work before, not sure what broke it or whether I used it in the wrong way. When the removeflag line is dropped *both* messages get flagged in the client, one in INBOX and one in Trash. With removeflag in place, *both* messages are unflagged, the one in INBOX and the one in Trash. This used to work differently before if memory doesn't fail me.

That should just work. I tested this with the indicated versions using 
sieve-test and an empty user account:

$ sieve-test -e -t - -Tlevel=matching ~/frop.sieve ~/message.eml

       ## Started executing script 'frop'
    6: address test
    6:   starting `:is' match with `i;ascii-casemap' comparator:
    6:   extracting `From' headers from message
    6:   parsing address header value `User <user at example.com>'
    6:   extracting `all' part from address `user at example.com'
    6:   matching value `user at example.com'
    6:     with key `user at example.com' => 1
    6:   finishing match with result: matched
    6: jump if result is false
    6:   not jumping
    8: addflag command
    8:   add flags `\Flagged $MailFlagBit1'
    9: keep action; store message in default mailbox
   10: removeflag command
   10:   remove flags `\Flagged $MailFlagBit1'
   11: fileinto action
   11:   store message in mailbox `Trash'
       ## Finished executing script 'frop'

info: msgid=unspecified: stored mail into mailbox 'INBOX'.
info: msgid=unspecified: stored mail into mailbox 'Trash'.
sieve-test(stephan): Info: final result: success
$ doveadm fetch flags mailbox "Trash" 1
flags: \Recent
$ doveadm fetch flags mailbox "INBOX" 1
flags: \Flagged \Recent $MailFlagBit1

So, that performs as expected. However, when I test this with LDA, Í can 
reproduce your problem:

$ doveadm fetch flags mailbox "Trash" 1
flags: \Recent
$ doveadm fetch flags mailbox "INBOX" 1
flags: \Recent

Will investigate more later today...

Stephan.
