This is what we use at work. Seems to do the trick - when you say doesnt work can you qualify that please?<br />

<cfmailparam name="Message-Id" value="<#createUUID()#@yourdomain.com.au>">

<div>
Thanks for the reply. Yes, I can!<br />
<br />
The Message-Id param inserted that way appears while the email is in the ColdFusion mail spool, but is overwritten by JavaMail as soon as the spool is emptied.<br />
<br />
The new Message-Id value is in the form: xxxxx.javamail.System@Mach<wbr />ineName. Where &quot;System&quot; is the account that runs the CF service and MachineName is the local name of the machine.<br />
<br />
It is confirmed by many posters on various sites. Have CF send you an email and check the Message-Id header. It will be different from what you have above.<br />
<br />
Thanks again.

Using CFMAIL, ColdFusion generates a Message-Id in the form xxxx@machineName, where machineName is the local name of the CF machine sending the email.<br />
It needs to be a Fully Qualified Domain Name (e.g. machineName.domainName.com<wbr />). <br />
How can it be changed from ColdFusion? (Using CFMAILPARAM Message-Id does not work)<br />
<br />
Thanks,

A web server refers to the software that helps to deliver web content that can be accessed either through the Internet or through an intranet. The primary function of a web server is to store, process and deliver web pages to clients. The communication between client and server takes place using the Hypertext Transfer Protocol (HTTP). The most common use of web servers is to host websites, but there are other uses such as gaming, data storage, running enterprise applications, handling email, FTP, etc.

Web Servers

Web development software is used to create websites for both the Internet and intranets. Software can be either locally installed or operated through a cloud interface, and ranges in complexity from simple text editors to full-fledged integrated development environments (IDEs) that include graphics, video, audio, scripting and database support.
