Ok. I apologise in advance if this issue has been addressed, I've tried to find it posted, but I can't.

I have the following problem with Links 2. When I try to send a newsletter I receive this message -


550-This message has 8-bit contents, but does not have the necessary MIME
550-headers. Sorry, this mail server does not accept mail without the
550-required MIME headers. See
550 for more information.
Message sent succesfully to ..(email address)



None of the newsletter emails arrive at their destination.
However, all the other mail things work well - including the mass email to link owners. I am a little confused as to why the newsletter won't work and everything else will. I don't really know anything about Mime headers, so I'm not sure how to go about fixing this problem.

I'd appreciate any advice.

Thanks,
Andrea.
