Subject says is all, right. 1.8b has this additional configuration variable. Not sure where to set it. Here is the description of its function in case you didn't know it was available: "In some cases, it may be desirable to filter a certain set of addresses for all lists, especially in the event of temporary problems with a gateway. This can now be done with the FILTER_ALSO configuration variable. It has the same format as the "Filter= Also,..." list header keyword, except that the wildcard specifications are separated by blanks, not commas. For instance, FILTER_ALSO = '*@*.XYZ.COM *@ABC.COM' will filter the addresses in question globally."
