Some of our e-mails send with coldfusion will be detected as spam. I found out after some google searching this is partly caused by the MessageID! And no one seems to have an solution ?
This message ID's look like:
Now the only way to reduce this detection dramatically - is to correct the wrong server name behind the "@" sign. This must be a FQDN or a IP by RFC! Maybe JavaMail only gets the local hostname and nothing more. I don't know how it is working - but this is for sure - *not* the complete name if i do a reverse DNS lookup... the reverse DNS gives me the FQDN of the machine!
So I must change the FQDN or the whole message-ID... I tried the <cfmailparam name="Message-ID" value="#createUUID()#@matchingpool.nl"> function but it does not change the message id . Is there any config option for this?
The box is a Windows 2003 Standard R2 Application Server ColdFusion MX 7.01 .
Exchamge 2003 SP2
Thank you for your help.
