When setting up Mailhosts, I get the error "Headers not found" when processing the account configuration e-mail. However, it's only happening on one of the hosts I am using, and not others.
The steps I take (which work for the other hosts) is:
In SpamCop's webmail interface, I click "Message Source", type Ctrl-A/Ctrl-C (select all / copy), close the tab, click the "mhreturn" URL, and paste the entire e-mail into the first box, and submit it.
For the other e-mail accounts I have set up, this works just fine. For this one host, I get the error "Headers not found". I have split the e-mail into header/body on that page, and I have forwarded the entire e-mail to the listed address, but they all give the same error.
I don't think I'm doing anything wrong (after all, it works for the other hosts), so I don't understand what might be wrong with this e-mail. I even replaced the one TAB in the header with spaces, but to no avail.
How do I proceed from here?
Thank you.
