I happen to be a sendmail old timer as well and will eventually follow the recommendations to migrate to Postfix. Can a kind soul out there provide the instructions to add TLD rejection to sendmail? Use the access DB. TLD blocking is in the example at https://www.sendmail.org/~ca/email/doc8.12/cf/m4/anti_spam.html#access_db Thanks, Bill. Just to be sure, the lines should look as follows: icu        REJECT info       REJECT site       REJECT stream     REJECT Right? BTW: I guess I have to read the access.db documentation closer. At this point I am confused. It seems that both the "From:" and "To:" headers are inspected. How is the differentiation made? TIA, -Ramon
