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
