Hi! We have some strange replication issues. Some mails are duplicated when expunged. This bug is quite hard to reproduce, it just happens occasionally. It seems somehow related to sieve. When i deleted the sieve script i could not reproduce this behavior.
Here are some logs, [email protected] is an alias for [email protected]: # Master Jun 23 00:51:41 dobby4 dovecot: lmtp([email protected]): copy from <lmtp DATA>: box=INBOX, uid=7816, msgid=<20160623005132EE517444BB$3A04DF25DD@ABRAHAM>, size=8933 Jun 23 00:51:41 dobby4 dovecot: lmtp([email protected]): 4N23HaMVa1fpmQEAJEBNLA: sieve: msgid=<20160623005132EE517444BB$3A04DF25DD@ABRAHAM>: stored mail into mailbox 'INBOX' Jun 23 04:52:57 dobby4 dovecot: pop3([email protected]): expunge: box=INBOX, uid=7816, msgid=<20160623005132EE517444BB$3A04DF25DD@ABRAHAM>, size=8933 Jun 23 04:52:57 dobby4 dovecot: dsync-local([email protected]): save: box=INBOX, uid=7817, msgid=<20160623005132EE517444BB$3A04DF25DD@ABRAHAM>, size=8933 Jun 23 04:55:21 dobby4 dovecot: pop3([email protected]): expunge: box=INBOX, uid=7817, msgid=<20160623005132EE517444BB$3A04DF25DD@ABRAHAM>, size=8933 # Replica Jun 23 00:51:42 dobby5 dovecot: dsync-server([email protected]): save: box=INBOX, uid=7816, msgid=<20160623005132EE517444BB$3A04DF25DD@ABRAHAM>, size=8933 Jun 23 04:52:57 dobby5 dovecot: dsync-server([email protected]): copy from INBOX: box=INBOX, uid=7817, msgid=<20160623005132EE517444BB$3A04DF25DD@ABRAHAM>, size=8933 Jun 23 04:52:57 dobby5 dovecot: dsync-server([email protected]): expunge: box=INBOX, uid=7816, msgid=<20160623005132EE517444BB$3A04DF25DD@ABRAHAM>, size=8933 Jun 23 04:55:22 dobby5 dovecot: dsync-server([email protected]): expunge: box=INBOX, uid=7817, msgid=<20160623005132EE517444BB$3A04DF25DD@ABRAHAM>, size=8933 The problem is the "dsync-server([email protected]): copy from INBOX: box=INBOX, uid=7817" on dobby5 at 04:52:57. This creates a new uid 7817 and the new mail is replicated back to dobby4. But i have no idea what triggers this copy. Any ideas? The dovecot version is 2.2.24. Thanks Dennis
