Emails showing as sent in Apple Mail but are not always received

I have an issue with Apple Mail where not all recipients are receiving emails.

The problem seems to be random in the recipients that are and are not receiving email. So for example, I recently sent an email to 8 people, 5 of them received it, and 3 did not. With the three that did not, even if I send them an email individually, they don't receive it. However, if I login to email on a browser and send via the broweser instead of through the Apple Mail client, they will receive it.

I have a number of accounts set up in Apple Mail, and these recipients don't receive email from me, no matter which account it is sent from.

A number of other colleagues who use Apple Mail are experiencing a similar issue.

Does this make sense? Let me know what further information is needed to try to diagnose the problem.

My first thought was that your eMail was falling into the Junk folders on some of your recipients' eMails so they didn't realise it had arrived, but I would have thought sending from the WebMail would have failed, too.

Do all the 'failing' eMails fall into some kind of category? Eg. Are they all iCloud accounts, or all BTInternet accounts, or all contain attachments, etc.?

Do all the people who are not receiving the emails have the same ISP?
