Nick,
Just to make sure I understand this correctly:
Say I am on a dialup account, with a new IP after every reboot.
If I reboot my computer, and immediately send a message to 'my' smtp server (mail.amazingfile.com) without first checking my email it will fail?
If, on the other hand, I reboot, check my mail (using pop authentication), and then send an email it will work?
If this is correct, then it is nicely configured! I feel safe again.
Gert
