can't you just put [EMAIL PROTECTED] in the kill file? thus breaking the
cycle. Then figure out what caused the loop to begin with, fix that, and take
excite's postmaster back out of the kill file.
AND are you the original poster of this? Just wondering, as it seems someone
has figured out how to mess around with imail list servers perhaps? send a
masqueraded from @exite.com to the [EMAIL PROTECTED] and start the cycle.
At any rate - isn't this a big problem with imail - the imailsrv alias should
never send mail out should it? That opens the whole loop up - heck I bet we
could launch the same kind of dos on ipswitch's list - maybe someone did, and
that is why this list is sooooo slow...
