Gmail servers not accepting mails

[Ram]

I was wondering if others on this list are also facing this , gmail 
breaking off some connections

All my postfix mailq is increasing because gmail , sporadically , times 
out some connections.

Jun  1 07:40:37 mmail14 postfix/smtp[17190]: 8D3CD5E6D00: conversation 
with gmail-smtp-in.l.google.com[173.194.79.27] timed out while sending 
RCPT TO
Jun  1 07:40:38 mmail14 postfix/smtp[17097]: 289895E6D0B: conversation 
with gmail-smtp-in.l.google.com[173.194.79.27] timed out while sending 
RCPT TO
Jun  1 07:43:24 mmail14 postfix/smtp[17196]: 682755E6AB4: conversation 
with gmail-smtp-in.l.google.com[173.194.79.27] timed out while sending 
RCPT TO




I think I will have to reduce the backoff time in postfix , so that 
postfix does not "learn" that gmail is not accepting mails


Thanks
Ram
