Please clarify:

Do you mean that the e-mails don't get delivered for hours, or do you mean it takes hours to transfer the e-mails from your e-mail server to your computer?

If it is the former, it is nothing to do with Thunderbird, but how e-mails go from server to server on the Internet before getting to where Thunderbird can download it.

If you are techie enough, you can look at the timestamps of the "Received:" headers of the e-mail.

Press Ctrl-u while viewing the e-mail to see the source of the e-mail and all the headers.

The "Received" headers are tacked on from bottom to top, so the last server to handle it is on the top. Compare that timestamp to the timestamp of the last "Received" header which was the first server to handle the e-mail. Also compare those timestamps to the "Date:" header, which was the time the sender's e-mail program recorded when the e-mail was sent.

thank you

This is a public forum, and that stuff you posted has your e-mail address. For the record, I didn't ask you to post it here publicly.

The heart of the matter is this:

X-Greylist: Delayed for 05:27:23 by milter-greylist-3.0 (champ.thecoop.net [216.218.255.169]); Thu, 19 Jan 2017 23:45:10 -0800 (PST)

This says that your e-mail provider (thecoop.net), delayed the e-mail for 5 hours, 27 minutes, and 23 seconds. This was due to a "Greylist" rule of some sort.

You, or whoever helps you with your website & e-mail hosting settings, set up the Greylist rule that did this. You need to change those settings.

I know this because your e-mail address is for a private domain name, and your e-mail address is the same one given for both the Administrative and the Technical contact information in the registration for the domain name. That information is available publicly.

Thank you for your help...you set me in the right direction and hopefully I will have this fixed in the next few days. Lol this is out of my league and I have a tech guy that I just reached out to.

grey lists generally fall into two categories. Mail coming from a site that has in the pat sent spam. Far more frequent that you might think with shared servers being used so there might be a dozen web sites using the same IP address as your site has.

The second is when a web site has not had the DNS records set up correctly or things like DKM signatures on the mail are just not present.

That you have reached out to your tech guy is good, web sites and mail are not really consumer level products. Despite what the likes of Wix tells everyone. There are some hosting companies that make such a mess of email hosting that some small businesses use web site hosting from one company and email hosting from another.
