Hi

Since Saturday I have been encountering issues when sending emails to certain email addresses where I am receiving the following message

his is an automatically generated Delivery Status Notification.
 
THIS IS A WARNING MESSAGE ONLY.
 
YOU DO NOT NEED TO RESEND YOUR MESSAGE.
 
Delivery to the following recipients has been delayed.

A few of these are emails where I have attached my CV as I am looking for a job and I could potentially be barried due to the time delay.

Can you please help me resolve this
