thanks Tom for that....
having a problem with relability and service at the moment in the office. even now and then the emails just stop receiving, when we contact the hosting co. they say there is nothing wrong from their end and like magic less than 5 mins later we start receiving again.... sound strange to anyone!!!! the problem is we lose all the emails that were in the queue whilst the system was down.... so we in effect don't know who or what we have missed - there is no email issued to anyone saying that it was not delivered.. (sorry not very technical ....)
