This would be an option if the mailserver is still capable of handling all or
some of the mail. As the question was raised, this is not the case. The
'theoratical' situation is that my mailserver is as dead as a doornail (not
really crashed but out of oxygen..network-bandwidth).
Thanks anyway for the response (and yes, the thread on fighting.... is indeed
very helpful for the case where I have some 'spare' bandwidth)
