Hi, I just moved mail spool to a different network storage. Now, several users are complaining about duplicate message that are fetched by their clients (Outlook, Microsoft Outlook). What is the reason?

This is my conf:

dovecot -n # 2.0.9: /etc/dovecot/dovecot.conf # OS: Linux

2.6.32-71.el6.x86_64 x86_64 CentOS release 6.6 (Final) auth_mechanisms = plain login digest-md5 cram-md5 disable_plaintext_auth = no first_valid_gid = 89 first_valid_uid = 89 mail_gid = 89 mail_location = maildir:/coraid-s2l2/domains mail_uid = 89 managesieve_notify_capability = mailto managesieve_sieve_capability = fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include variables body enotify environment mailbox date imapflags notify mbox_write_locks = fcntl namespace { inbox = yes location = prefix = INBOX. separator = . type = private } passdb { args = /etc/dovecot/dovecot-sql.conf.ext driver = sql } passdb { args = /etc/dovecot/dovecot-sql-crypt.conf.ext driver = sql } plugin { sieve = ~/.dovecot.sieve sieve_dir = ~/sieve sieve_extensions = +notify +imapflags sieve_max_script_size = 1M } protocols = imap pop3 lmtp sieve ssl_cert = </etc/nginx/ssl/wildcard.server.net.crt ssl_key = </etc/nginx/ssl/wildcard.server.net.key userdb { args = /etc/dovecot/dovecot-sql.conf.ext driver = sql } protocol lmtp { mail_plugins = } protocol lda { mail_plugins = }

Hello,

Please check if those users have X-UIDL header in their emails. If do, remove header. That should solve the problem.
