Any time I have ever had problems with access.db's aliases etc etc.. It was always the same thing. A problem in sendmail/makemap Usualy getting makemap to the proper version solved it. Also running sendmail -bi to remake the alias.db I would check the date and versions of makemap and sendmail to see if they are the same. Keith ================================= Keith W.
