he is a road runner dhcp client. i would like to create a system account for him for his domain and have him receive/send thru my server.
i would like him to authenticate with ssl if possible. i would like to set stuff up for about 4-5 other people to do this, but dread adding mysterious *libs andstuff and ultimately having nothing work for anybody. everything currently works perfectly! is there a tutorial for this type of situation? thanks for you help! vora > -----Original Message----- > From: [EMAIL PROTECTED] > [mailto:[EMAIL PROTECTED]]On Behalf Of Mike Burger > Sent: Thursday, August 15, 2002 6:16 AM > To: [EMAIL PROTECTED] > Subject: Re: postfix woes > > > You don't "have to start relaying mail for him at his apartment"...but > you could, if you wanted to.
