Hi all, As my machine running qmail is named senfpott.gysar (a bogus name, used only in our local network), it should masquerade any outgoing mail to [EMAIL PROTECTED] Now - as explained in the faq - I put gymnasium-sarstedt.de into control/defaulthost. It worked - until I configured serialmail. Now qmail seems to just ignore defaulthost, no matter whether the mail is to a local or a remote address - it always shows <from: [EMAIL PROTECTED]>. I already tried to change all the senfpott.gysars into gymnasium-sarstedt.de (in me, defaultdomain etc.) which 1st isn't a good practice at all and 2nd doesn't help either. Of course I already checked if there's an environment variable set that overrides defaulthost, but there is none. Any help? Sebastian Steinlechner
