Help Mailer code change for new server ?

I have just changed to a new server and the asp on the site works fine but the mail part won't run(worked fine on the old server). I have spoken to Fasthosts and they tell me they support jmail, cdonts and cdo. I guess it's the mail sender that is not supported? The code I have is as follows. I am hopeing that it would be easier to adapt the code rather than write a new script which would be a problem for me, given my abilities with asp.

<%
dim firstname, email, can_we_help, Tmonth, Tday, Tyear, transfers
dim adults, children, accomodation, nights, referred_by, ref_other, Mailer

firstname = request.form("firstname")
email = request.form("email")
can_we_help = request.form("can_we_help")
Tmonth = request.form("Tmonth")
Tday = request.form("Tday")
Tyear = request.form("Tyear")
transfers = request.form("transfers")
adults = request.form("adults")
children = request.form("children")
accomodation = request.form("accomodation")
nights = request.form("nights")
referred_by = request.form("referred_by")
ref_other = request.form("ref_other")

' Creating the mail component's Instance.
Set Mailer = Server.CreateObject("Persits.MailSender")

'Saving sender's information in mail object properties to send it to Server.
Mailer.FromName = firstname ' Mail sent from name.
Mailer.From = email
Mailer.Host = "localhost" ' Mail server Address.
Mailer.AddAddress "enquiries@mydomain.co.uk"

Mailer.Subject = "Property Enquiry"

' Formating the information got from above declared variables in order to send it to specific address.
Mailer.Body = "mycompany" & vbcrlf & vbcrlf+_
