domain related mail

[Roar Thronęs <roart@nvg.ntnu.no>]

Hi

One of our domains will cease to exist later this year, and mail to that
domain will surely bounce then.

We would prefer giving those who now send mail to that domain an automatic 
notification about changing the email address, while the receiver gets
mail as usual.

Anyone who has ideas of how to implement such a thing?

(We are using cvs990308.)

Thanks in advance.
