dovecot - Jan 2014 - Replication file sizes

Hi,

I'm using Dovecot 2.2.9 to replicate my mailbox to a remote server.

My mailbox on ServerA is 235Mb, but on ServerB it ends up being 358Mb.

Does anyone know why this is?  Shouldn't they be the same size?



doveconf -n from ServerA:

# 2.2.9: /usr/pkg/etc/dovecot/dovecot.conf
# OS: NetBSD 5.2 cobalt
auth_mechanisms = plain login
doveadm_password = secret
doveadm_port = 12345

last_valid_uid = 1020

mail_location = mbox:~/mail:INBOX=/var/mail/%u
mail_plugins = " notify replication"
passdb {
  driver = passwd
}

  mail_replica = tcp:serverb.test.com
}

  unix_listener /var/spool/postfix/private/auth {
    group = postfix
    mode = 0660
    user = postfix
  }
  user = root
}
service doveadm {
  inet_listener {
    port = 12345
  }
