I am testing Open Source 5.0 zimbra and it was working fine for a few weeks but
when I started working on backup (using a perl script I found in the wiki) all mail is
being deferred. I have restarted zimbra a number of times and have turned off AV
I have plenty of space in my tmpfs device (700M plus 0 used). I only have a single user on and have a split domain with zimbra the slave (is-smtp-1 is the smtp server that has aliases for both post office systems, one running zimbra the other (production) running courier.

the following is the log for a single message)

thanks
