Sieve replication - does not replicate

Hi,

I have two servers replicating mail as required, the directory structure 
(per user), however they will not replicate the sieve scripts directory:

server 1

Maildir sieve

server 2

Maildir

Output of doveconf -n on server 1:

The only error message I can see in the logs (/var/log/mail.err) is, 
this is not for every user and is only occasionally:

Sep 30 14:46:34 imap2 dovecot: 
lda(a_user)<1306><f0JXJjoHkl0aBQAAZJ7A9A>: Error: sieve: Failed to 
initialize script execution: Invalid postmaster_address: invalid address 
`postmaster@' specified for the postmaster_address setting

Any suggestions would be much appreciated.

Cheers
