I don't see any retries happening in the mail log; mail is taking up to 
5 minutes to be delivered in some cases but it all seems to be getting 
through at the first attempt. I don't see anything unusual in the 
procmail log either. If you're having DNS issues then I agree that it 
would be a good idea to set up and use a caching nameserver on your own 
system.
