For backup all input and output mail i use postfix bcc_maps configuration.
We have mailboxes "in_backup@domain.name" for input mail and "out_backup@domain.name" for output mail. In postfix config file "main.cf" added next options:

sender_bcc_maps = hash:/opt/zimbra/postfix/conf/sender_bcc_maps
recipient_bcc_maps = hash:/opt/zimbra/postfix/conf/recipient_bcc_maps

@domain.name out_backup@domain.name

@domain.name in_backup@domain.name

This config works fine with zimbra versions from 6 to 8.0.1. But after upgrading to 8.0.2 i have problems.
Mailbox out_backup@domain.name works correct, but in mailbox in_backup@domain.name we have all mail (input and output from server)! This problem start with upgrade to 8.0.2, and version 8.0.3 did not fix that! Also, we have additional web-interface lag in e-mail send process (20-30 seconds).

Can anybody help with fixing this bug?
