Email forwarding - delay of 2 hours or more

I forward all my iCloud emaiIs to my gmail account and have a colleague whose emails sometimes are delayed by up to 2, 3 or 4 hours. The Google Toolbox header checker shows that this delay occurs between the Apple Mail Server and the Gmail server:-

4 hours mr85p00im-zteg06011601.me.com. → [Google] mx.google.com

The only clue I can see as to why this should happen is that is that the header shows a "dmarc=fail" entry as follows (email address edited with xxxxxx's for privacy):-

17.58.23.186 as permitted sender) smtp.mailfrom=xxxxxxx@hotmail.co.uk;

dmarc=fail (p=NONE sp=NONE dis=NONE) header.from=hotmail.co.uk

Return-Path: <xxxxxxx@hotmail.co.uk>

They always come through in the end, but could these emails be held back because of this?

Is there any other reason for this behaviour?

Thanks for any thoughts

Sent mails showing in iCloud Mail Inbox, but only on Mac Mail I have iCloud mail with a custom domain. I read/send mail on Mac, iPhone and iPad, and once/while on icloud.com - and everything usually syncs fine. But a couple of times a month, Mac Mail decides to show COPIES of my most recent 2-3 Sent emails (but no more) in my Mac Mail INBOX. Often the emails were sent a few days/week ago - but then all of a sudden a few just show up in Mac Mail Inbox. This am (12/4), an email sent on 11/29 just showed up in Inbox. It wasn't there yesterday. No I did not BCC, and it is only the last 1-3 Sent emails, not the entire Sent folder. I've checked Mail Preferences and View/folder settings, and nothing I've changed fixes it. FYI, they also are not showing on iPhone/iPad/iCloud Inbox, only Mac Mail Inbox, so iCloud seems to be synching fine. So that tells me it's a Mail display bug? 2020 M1 Air, Ventura 13.0.1, Mail 16.0
