Why is my sent email delayed 30 seconds? Suspect DNS server.

Maybe your time stamp sources are just out of sync by 30 seconds. What are you basing this difference on? IF its a busy mail server 30 seconds isn't all that unusual is it?

Hi hotei, timing done by system clock ticking off the seconds. Normal elapsed tine is about one second. - jamescash on October 1, 2010
Some email companies use to send emails in batches, so maybe every 5 minutes they send all emails, that were 'sent' in those last 5 minutes, or here 30 seconds. But almost no one does that anymore
gmail was a way to undo send, if the feature is enabled, where it just waits, 3 to 30 seconds, before sending the email. In that time you can hit a cancel button if you realized you've made a mistake.
Whats the domain (@applemail.com or what?), the mail client your using, are you sending the email to yourself, and anything you can tell us about your setup that might be buggered.

Thanks alpha1, domain is comline.com, using Apple Mail POP, sending to myself and others. Consulted with Apple Genius who deleted a preference file resulting in normal behavior in the Apple Store. Fail back home. The research continues. Current hypothese is fault in our ISP/street network cabling or some 'policy' setting in postfix. - jamescash on October 1, 2010
ok, so then try using a proxy or logging into your email somewhere else, like a library or work, and see if you have the same problem. - alpha1 on October 2, 2010
Thanks alpha1, situation remains unchanged. Discovered no postfix policy setting that would cause slow smtp response. I agree trying other locations can be useful. Meanwhile, I may change DNS settings using OpenDNS and Google's DNS set. Our ISP may have a firewall set. - jamescash on October 5, 2010
Your ISP should have to tell you if they do, so give them a call as ask their policy on it all. - alpha1 on October 15, 2010
We are in contact with our ISP and they are searching for an answer. If a solution is found, I will post. - jamescash on October 18, 2010

Could you provide some more context? What version of MacOSX, what MacBook, what wireless router, etc? - digitxp on September 26, 2010
Define what you mean by delayed. It could be a grey-listing issue, it could be batched email processing, it could be a lot of things really. - MaQleod on September 26, 2010
Hi digitxp, Using OS X 10.6.4, 2008 iMac, no wireless router, just a cable modem. I agree could be a grey-listing issue. Will investigate. ISP has checked its settings. Cable guy looked around the house and replaced a splitter resulting in no change in behavior. - jamescash on October 1, 2010
