If you have any ideas why and can come up with a fix, that would be better.

That's a bit odd. Is it only doing that on certain email addresses or any email addresses? I'm a bit stumped at this point as it doesn't make much sense. Can you send the email here to me in aPT or does it do that to you here as well?

What I sent you by PM doesn't work for me at my forum.

As you are a member there, you may wish to test it out there for yourself.
