is mx5.realemailserver.net your server, and is it running postfix? if
so, look at header_checks to see if one rule is rejecting the message.

we can't help much as long as you can't show unaltered, unedited,
un-obfuscated infos.

PS. do not CC me when you send from nabble. I will make no exception for
nabble to send mail on behalf of gmail as long as they can't crack gmail
DKIM keys ;-p
