Posting a list  at a time does  NOT avoid the spam filter,  it just takes
longer for the filter to take effect,  because it can't know it is a spam
until  it has  received  (and  accepted) a  certain  number of  identical
copies. If you post to 100 lists at once it sees the long "To:" field and
bounces  right away.  Besides, UB  runs 1.8a  and doesn't  have the  spam
filter :-)
