Let me rephrase my question when a user on a virtual domain domain2.com send an email via the server host domain1.com, will smtp identify itself as Domain1.com or Domain2.com? does the answer depends on whether the user authenticated or not ?
If the answer is Domain1.com, then the "from" [EMAIL PROTECTED], will be different from the ehlo/smtp/PTR Is that tested by some servers ? can it be a problem ? ----- Original Message ----- From: "Len Conrad" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Friday, October 10, 2003 11:32 PM Subject: Re: [IMail Forum] PTR record for a virtual IP > > >there was a thread about supanet last week, and how they check the ehlo > >against PTR. > >in their case, it will not be possible to send them a email from a virtual > >host. > >correct? > > no.
