I must say I was a bit sceptical if this sieve script would resolve it, but it seems like it totally did! Thanks a lot for your reply, hope this helps someone else in the future as well.
Kind regards,

ok duplicsate emails (even across dsync, replication etc) is typically handled via a global sieve script
I use :
# cat duplicates.sieve require "duplicate"; # for dovecot >= 2.2.18
if duplicate { discard; stop; }
for the scripts
and setup sieve to work via my dovecot.conf file
relative parts below :
protocols = imap pop3 lmtp sieve
protocol lmtp { mail_plugins = $mail_plugins sieve postmaster_address =monitor@scom.ca }
protocol lda { mail_plugins = $mail_plugins sieve }
plugin { .....
sieve =file:~/sieve;active=~/sieve/.dovecot.sieve sieve_duplicate_default_period = 1h sieve_duplicate_max_period = 1d sieve_extensions = +duplicate +notify +imapflags +vacation-seconds sieve_global_dir = /usr/local/etc/dovecot/sieve sieve_before = /usr/local/etc/dovecot/sieve/duplicates.sieve..... }
service managesieve-login { process_limit = 1000 vsz_limit = 1g inet_listener sieve { port = 4190 } }
protocol sieve { managesieve_implementation_string = Dovecot Pigeonhole managesieve_max_line_length = 65536 }
note the sieve_before which handles duplictes during delivery etc.
Happy Monday !!! Thanks - paul
