You need a Cw line for each official name you have. So for example, if your "official" name is aiki.addease.com.au and your "unofficial" name is aiki.internal.lan, you'd have Cwaiki.internal.lan Cwaiki.addease.com.au Put these lines in your .mc file - or directly into sendmail.cf, but the .mc file is better :-) See /usr/src/usr.sbin/sendmail/cf/README. You may also need to MASQUERADE_AS(aiki.addease.com.au). -- Brian <brian@awfulhak.demon.co.uk> Don't _EVER_ lose your sense of humour....
