I am new to Cox services, and am seeking information relative to processes that cause e-mail delays inbound. My quest is to understand if this circumstance is something I must accept and adapt to for all emails.
Specifically the Following:

Which clearly illustrates the delay between 2 internal cox_labeled servers.
Is this the 'normal way' cox rolls, delay_wise?
Could you explain what that header is for? Inbound from normal Gmail to Cox? Or is this a relay from your personal domain(using Gmail as MX) to a Cox email?
Here is, I hope, a better view of the hops.....

This isn't a big deal, I just wanted to know if this is 'normal', for cox-mail now that they appear to be using oxcs.net resources, and FWIW, that appears to be where the delay really is. It WOULD be helpful to know if this delay is consistent for all email transiting to oxcs.net hosts.
I think this is a rare case of a post having too much technical data, and not enough simple explanation. You are asking if something is normal, and then showing headers and hops, but you aren't explaining what they are for. Are you sending from a Yahoo.com webmail client to Cox? Is it a yahoo custom domain? Is it Oath account through Verizon/AOL?
The reason I ask is sonic.gate.mail.ne1.yahoo.com is has a spam reputation, so it's possible they are doing a IP check each time you send, which is slowing it down. One way to test that is to send from a different source and compare. It is very difficult to gather anything from your data without that context. If there are privacy issues, then express them, but in such a way that give some kind of background on the issue. I am not a robot. You can speak to me like a normal person.
