Then just delete the 20K messages from the queue using postsuper within a
script and reset the password on the compromised account. There's an
example script in the postsuper man page for deleting all messages in the
queue addressed to a given recipient. You should be able to easily modify
it to delete all messages from a given sender. Something like this maybe:
mailq | tail +2 | grep -v '^ *(' | awk 'BEGIN { RS = "" }
# $7=sender, $8=recipient1, $9=recipient2
{ if ($7 == "[email protected]")
print $1 }
' | tr -d '*!' | postsuper -d -
