Hi harbutt,

This is an issue to take up with your email service provider.  Something about the messages you are sending is causing them to be rejected by the servers' antispam filtering.  Due to authentication requirements, sending through a separate account can often cause problems, as most ISPs now will only accept messages sent from an account with them.

@harbutt, as @SendOfJive has already alluded to, that SMTP response is being generated by one of our outbound mail servers. The long string of characters is a spam fingerprint that's being matched by the Cloudmark anti-spam appliances we use.

Chances are it's the domain you're trying to send to or a URL in the content of the email that's triggering the detection.

If you're still having problems then try sending the message using our Webmail platform. It should faile with a similar message and end up in your drafts folder.

If you then raise a support ticket explaining the situation then we can log into your account, take a look at the email and try to establish what's causing the problem.

Hope that helps.
