Why the difference in email transit times?

[Tedd Sperling]

Hi gang:

I'm using the class.phpmailer.php code to send email -- it works neat -- very classy (no pun intended).

I can send an email from my sperling.com domain and it arrives almost immediately.

However, when I use the exact same code (except for the FROM address) from kvyv.com (another domain I own), the email literally takes hours (up to 12) to arrive.

Any idea of why there is a difference of email transit times between the two domains?

Cheers,

tedd

PS: Note, my receiving email addresses are handled by gmail.com.

Hi,

Have a look at the "Received:" headers of each email. They are in
reverse order. I.e. the one at the top is the most recently added.

Take into account timezone differences too.


12 hours seems like a very long time for a delay. I suspect one of the
receiving hosts in the chain employs greylisting, and the sending
network employs many different sending servers (ie like Google) in a
round-robin fashion. The greylisting server may not be configured to
recognise the many different servers as one 'set'.

All speculation of course ;)

Feel free to send the headers off list and I'll take a look.

Regards

Ian
