Sporadic "Undelivered Mail Returned to Sender" emails



I've been receiving random returned email messages as follows:


"This is the mail system at host


I'm sorry to have to inform you that your message could not be delivered to one or more recipients. It's attached below.


For further assistance, please send mail to postmaster.


If you do so, please include this problem report. You can delete your own text from the attached returned message.


                   The mail system


<>: host[] said: 558

    5A1DA3140AFE3791 Message content rejected due to suspected spam. IB703 (in

    reply to end of DATA command)"


This is happening randomly, not all sent emails and they are all addresses that I correspond with weekly at the very least. I know there is nothing wrong with the email address. This issue has come about since I received a notification from Optus that I was getting close to exceeding my 500MB quota. I went onto my webmail (which I never do) and cleared a load of emails to make space (thinking this would not replicate inside my Outlook 2016 as I assumed it would keep a local copy there but it also deleted them too). Anyway, I am now getting this frustrating situation with emails bouncing. 


Any clues friendly peeps?
