Need help with the following erro form postfix

Hi,
I'm currently using Zimbra 4.5.1 I have setup 2 servers in 2 different locations as master/slave one in a remote location and one on our local LAN with the user inboxes on it.
When I try and send an email to a list of more than 20 people created in the admin panel I get the following error from mail.info
Feb 23 11:15:43 mail-leb postfix/smtp[5103]: 52D1A61C05F: to=, orig_to=, relay=127.0.0.1[127.0.0.1], delay=1253, status=deferred (host 127.0.0.1[127.0.0.1] said: 450 4.4.2 Timed out during fwd-rcpt-to, 000 , MTA([127.0.0.1]:10025), id=04546-01 (in reply to end of DATA command))
And the following from zimbra.log:
Feb 23 11:15:40 mail-leb amavis[4542]: (04542-01) (!)FWD via SMTP: ->

BODY=8BITMIME 450 4.4.2 Timed out during fwd-rcpt-to, 000 , MTA([127.0.0.1]:10025), id=04542-01

Feb 23 11:15:40 mail-leb amavis[4542]: (04542-01) Blocked TEMPFAIL, [82.205.159.211] [82.205.159.211] ->

Message-ID: , mail_id: afRL3G-GEJrK, Hits: -4.266, 89662 ms
All the users in the list have their inboxes defined on the server connected to the local LAN. This error appears both when sent from outlook or the web interface. The DNS server is configured on the mail server itself and is working correctly.
If I stop amavisd with the following command: zmamavisdctl stop

I get a Connection refused from on MTA delivery. However I would like this to work with amavis enabled.

Any reason why amavis would behave like that!
Any help in that matter would be greatly appreciated!
Regards,

Samer

No idea what that means.

Update on the situation.
After disabling amavisd emails get delivered fine.
Once re-enabled I set the debug mode to 3 the problem appeared clearer, for every email in the list amavis sends an RCPT-TO at a very slow rate and is causing it to time out leading to smtpd deferring the message.
Is there any way of telling amavis not to perform RCPT checks?

As the problem above states it seems that amavis takes a long time getting RCPT TO answers for every email in a list which is causing smtpd to time out when amavis returns the message to postfix.
I really like zimbra and are currently considering deploying for a large ISP and all support is most welcome!
