Classic ASP Mail - Error send to user and admin - email

Question

I am sending a mail using CDO.Message. When the user submits a form, the form details to be sent to the Web Site Owner and a Acknowledgement mail to the user. The later is not working for me. I have repeated the same code twice by changing the configuration names, I simply get "Internal Server Error"
My Code (mail to the Web Site Owner)
<%
name = Request.Form ("name")
email = Request.Form ("email")
phone = Request.Form ("phone")
message = Request.Form ("message")
Dim iMsg, iConf, Flds, vSub
Response.CodePage = 65001
Response.CharSet = "utf-8"
Set iMsg = CreateObject("CDO.Message")
Set iConf = CreateObject("CDO.Configuration")
Set Flds = iConf.Fields
'sending email with Google Apps Premium SMTP server (with autentication)
schema = "http://schemas.microsoft.com/cdo/configuration/"
Flds.Item(schema & "sendusing") = 2
Flds.Item(schema & "smtpauthenticate") = 1
Flds.Item(schema & "smtpserver") = "localhost"
Flds.Item(schema & "smtpserverport") = 25
Flds.Item(schema & "sendusername") = "info#priceakagri.ru"
Flds.Item(schema & "sendpassword") = "******"
Flds.Update
With iMsg
Set .Configuration = iConf
.BodyPart.Charset = "utf-8"
.To = "info#akagri.ru"
.From = "info#priceakagri.ru"
.Subject="Message from Priceakagri.ru contact page"
.HTMLBody="Здравствуйте! <br><br>You have received an Enquiry from <font color='#337AB7'><b>" & Trim(Request("name")) & "</b></font>.<br><br><br><table><tr><td width='30%' colspan='2' bgcolor='#337AB7'>Message Details</td></tr><tr><td>Name</td><td>" & Trim(Request("name")) & "</td></tr><tr><td>Email</td><td>" & Trim(Request("email")) & "</td></tr><tr><td>Phone</td><td>" & Trim(Request("phone")) & "</td></tr><tr><td>Message</td><td>" & Trim(Request("message")) & "</td></tr></table>"
Set .Configuration = iConf
.Send
End With
set iMsg = nothing
set iConf = nothing
set Flds = nothing
%>
The above code works perfectly for me. If I replicate the same and send user a mail on acknowledgement, I get error. I used the users email as .To and From as - info#priceakagri.ru
I have done this in my earlier sites, where I include a .txt file for the later and still is working for me.
Need help.
