sed prepend text ?

Hi,

I have a file with email header information. I would like to change the Subject line.

Code:
Subject: ** PROBLEM Host Alert: server.domainname is DOWN **

I'd like to change this line such as to look,
Code:
Subject: serverID ACK Fw: ** PROBLEM Host Alert: server1.domainname is DOWN**

How can I edit this? sed or anything else is fine.

Note: server1.domainname, is not always constant it could be server2, server3.domainname up until server30.domainname

domainname(8)						      System Manager's Manual						     domainname(8)

NAME
domainname - set or display name of current domain nisdomainname - set or display name of current NIS(YP) domain ypdomainname - set or display name of current NIS(YP) domain SYNOPSYS
domainname [ domain ] nisdomainname [ domain ] ypdomainname [ domain ] DESCRIPTION
Without an argument, domainname displays the name of the current NIS domainname of the system. domainname uses the getdomainname(2) function for getting the domainname, nisdomainname and ypdomainname are using yp_get_default_domain(3). Only the super-user can set the name of the domain by specifying the new domain as an argument. All three programs uses setdomainname(2) for this. Bear in mind, that already running programs may continue to use the old domainname. SEE ALSO
getdomainname(2), setdomainname(2), yp_get_default_domain(3), ypbind(8), ypcat(1), ypmatch(1), ypwhich(1), yppoll(8), ypserv(8), yset(8) AUTHOR
