Exim config. question

[Zxin]

How can I force Exim to respond as the virtial domain its serving for.

IE:
telnet server1.someISP.tld 25

220-server1.someISP.tld ESMTP Exim 4.52 #1 Tue, 21 Mar 2006 14:43:45 -0800
220-We do not authorize the use of this system to transport unsolicited,
220 and/or bulk e-mail.

Where it would be nice to have it do this:
telnet someHostedDomain.tld 25

220-someHostedDomain.tld ESMTP Exim 4.52 #1 Tue, 21 Mar 2006 14:43:45 -0800
220-We do not authorize the use of this system to transport unsolicited,
220 and/or bulk e-mail.

I have done this with sendmail in the past, and would like to do this with Exim.

AFAIK, you can't - the banner is meant to show the hostname of the server and should always be consistent with that. If it is possible, you'd find it over at www.exim.org
