Royal Mail has made a statement on its website with full details: http://www.royalmail.com/portal/rm/content1?catId=1000002&mediaId=23600684

According to the website (on 14/02/2005), items posted in Northern Ireland for delivery to Great Britain (and including international items and those for the Republic of Ireland) are not being dispatched. Most mail to Northern Ireland from Great Britain and other parts of the world should, however, be delivered – with the exception of North, South and West Belfast. East Belfast remains unaffected although there will inevitably be less mail for delivery.

Royal Mail in Northern Ireland is unable to accept any further Special Delivery, including International Airsure, items with immediate effect. Items already accepted at Post Office branches will not receive a full service and no more will be taken in.

If you are in a trading relationship with someone who might be affected, please be mindful that payments being sent by post or items dispatched by post are likely to be delayed until the dispute is resolved. It is advisable to inform your trading partner if you are aware that you have been affected. If you are awaiting a payment or delivery of an item, please be patient.
