kt -> SPF record (7/29/2006 9:56:49)
My hosting company has just added an SPF record for my domain, but only for my mailserver. They then said this: "I did not include your actual websever as a mail sender as I believe it would only be your actual mailserver which is used to send any mail. Please let me know if your site actually sends out email for this domain too." I'm not sure of the answer to this, and I couldn't get a straight answer from the hosting company. I run scripts on many of my pages that send mail with CDO, for example to notify members of things, for contact forms, that sort of thing. Does this mean that I use my webserver to send mail too? Many thanks, kt

It is on the hosting company unless you use a co-located server. It is a server level configuration. If using a standard web hosting account this would not be on you. Here is a good site that goes over it all... http://www.openspf.org/ In that site is a link to a "checker" to see if it is allready setup... http://www.kitterman.com/spf/validate.html Take care, Brian

Are they on the same physical machine / IP address? If they are, you're all set. If not, you will need to 'point' all your CDo mail thru your mailserver first to take advantage of the SPF record. A ReverseDNS entry is also recommended and more widely supported than an SPF record (currently anyways until Microsoft takes over the world.[:D])

Thanks both for the replies. I think I will have to send CDO email using my mailserver.

So, if I use something like this (which seems to work):

<%
Dim ObjSendMail
Set ObjSendMail = CreateObject("CDO.Message") 
ObjSendMail.Configuration.Fields.Item ("http://schemas.microsoft.com/cdo/configuration/sendusing") = 2 
ObjSendMail.Configuration.Fields.Item ("http://schemas.microsoft.com/cdo/configuration/smtpserver") ="mail.mysite.com"
ObjSendMail.Configuration.Fields.Item ("http://schemas.microsoft.com/cdo/configuration/smtpserverport") = 25 
ObjSendMail.Configuration.Fields.Item ("http://schemas.microsoft.com/cdo/configuration/smtpusessl") = False 
ObjSendMail.Configuration.Fields.Item ("http://schemas.microsoft.com/cdo/configuration/smtpconnectiontimeout") = 60
ObjSendMail.Configuration.Fields.Item ("http://schemas.microsoft.com/cdo/configuration/smtpauthenticate") = 1 
ObjSendMail.Configuration.Fields.Item ("http://schemas.microsoft.com/cdo/configuration/sendusername") ="mymail@mysite.com"
ObjSendMail.Configuration.Fields.Item ("http://schemas.microsoft.com/cdo/configuration/sendpassword") ="mypassword"
ObjSendMail.Configuration.Fields.Update
ObjSendMail.To = "someone@somesite.com"
ObjSendMail.Subject = "Subject"
ObjSendMail.From = "someone@mysite.com"
ObjSendMail.TextBody = "Body"
ObjSendMail.Send
Set ObjSendMail = Nothing 
%>

...is there any danger of anything malicious being done with my email address and password, given that it's included in the code for outgoing authentication?

Are there any other advantages/disadvantages/issues of using the remote mailserver versus localhost?

Thanks again, kt
