We are experiencing an issue whereby some users are receiving emails after a very long time period. Mails are being sent via a PHP application.
I want to understand if what I am seeing is normal & expected.
Below is the message header for one such email (names changed to protect the innocent). It seems to me that it took 27 minutes for my server to send the email. Is that correct? Then it took the recipients mail system another
18 minutes to deliver the message to the inbox. Is that assumption correct?
And, if I'm correct, are there some obvious things that we can do to deliver email faster?
Thanks for your (expert) eyes!
