In thiis day and age, email is becoming more and more unreliable. Mostly because of failed attempts to block spam and spammers, but that's not what I wanted to ask about.
Some mail errors are genuine; there was a real problem with delivering the mail (even if it is "we don't acceptt mail from you because of "reason X"), others happen because of butterfingers; the user managed to mistype his email address.

Is there a way to configure Geeklog (1.4x) so that the user will get an error message if the conformation mail failed? While the user is still on the new registration page, I mean.
