Get INVALID_MSGID Message-Id is not valid, according to ...

Hi,

I successfully sent some emails using SwiftMailer, but noticed when I checked in one of my web-mail systems that it had scored 2.6 in SpamAssassin because:

2.6 INVALID_MSGID Message-Id is not valid, according to RFC 2822

I would ideally like to avoid this, so I checked the headers and it says (X where numbers should be):

Message-Id: <XXXXXXXXXXXX.XXXXX.XXXXXXXXX.swift@Linux infong 2.4 #1SMP Tue Dec 18 22:35:15 UTC 2007 i686 GNU/Linux>

Could anyone tell me what is wrong and how I can change this? Is it because it is not a real address?

Thank you.
