Royal Mail continues to experience severe service disruption to international export services following a cyber incident late last week.
At the moment, Royal Mail are temporarily unable to despatch items to overseas destinations.
"In order to prevent a build-up of export items in its network and support a faster recovery when we restore service, Royal Mail is continuing to ask customers not to post international export items until further notice," Royal Mail declared on its website earlier this week.
According to Royal Mail, items that have already been despatched may be subject to delays.
An investigation into the incident is ongoing and Royal Mail are working with external experts and have reported the incident to its regulators and the relevant security authorities.
