Here's an issue I've been seeing more and more lately. We conduct a lot of day-to-day business through e-mail. I've noticed, that when an email is sent to user1@domain.com, user2@domain.com, and user3@domain.com that e-mails to just one user sometimes don't get delivered until after a few hours.
For example, there was an e-mail addressed to 3 recipients. The first user got the e-mail within 5 minutes of being received...that's good. The second user didn't get the email until 2 hours after. Since it's been happening more and more, I decided to discuss this with you guys. Do you have an answer?
