Presumeably the (tower.stc.housing.washington.edu) comes from a PTR DNS lookup. What happens if the IP address of the remailer isn't available from DNS, or the in-addr.arpa entry is wrong? (I don't know who exactly is responsible for the in-addr.arpa entry--is it the same as for the others?) --Paul J. Ste. Marie pstemari@well.sf.ca.us, pstemari@erinet.com
