[TYPO3] Directmail detected as spam

[sd at ixnl.com]

Hi

Just got Directmail going - lovely.

I sent out the new mail to all in the list (all registered users to the site)

A lot of them come from one provider, but now this provider is bouncing all mails I send to users saying SPAM DETECTED.

How do I resolve this, or can I?

I need to get UNSPAMMED from them and want to make sure it doesn't happen with other providers etc? How?.

Is there a way, or should I just go back to mailman which I was using for years without any problem.

I am sooo unhappy ;(

Regards Stan
