Routing issue with GMAIL.com

From last week onward no outbound mails are transferring to GMAIL.com from our Domino server. The only issue is with GMAIL.com. Rest of the mails are transferring without any issueWe are using Domino server 6.5.6

Tell router show queue says

1 Retry( 2) SMTP GLAMIL.COM (Push)

                  Next retry: 05/21/2009 10:02:49 AM

I can see following log in log.nsf

5/21/2009 09:17:58 AM [0CDC:001D-0E74] SMTPClient: Connection terminated with status: 2562

05/21/2009 09:17:58 AM Router: No messages transferred to GMAIL.COM (host gmail-smtp-in.l.google.COM) via SMTP

Any suggestion & Ideas will be highly appreciated
