Good day all! This is a follow-up on my earlier e-mail. Chase Giles was correct: it was not what we thought it was. It was a case of mailboxes being full and the system just keeps on resending error messages. :( My thanks to those who sent replies privately or via the list, like J.D. Falk, Chase Giles and Phil Howard. My sincere apologies to Myriad.net for their trouble. William
