Hope someone can help with this maddening problem.
I am using Outlook XP on a laptop and if I send emails to Italy, Germany, Norway etc I have no problems. If I send emails to contacts in Iran and Poland and I believe a couple of other countries the emails are moved from the outbox to the sent folder but they are never recived at the other end.
It cannot be my ISP because I can email the contacts in Poland and Iran from my desktop PC which runs W98 and office 97 without any problems. Any replies would be appreciated
