Hi,
Since 2 days we have trouble sending to a handfull of domains. Even when sending just a plain text mail, we get a generic error like this back:
5.3.0 - Other mail system problem 550-'Administrative prohibition'
I have contacted one of the mail admins and he saw it was confirmed as spam: ctasd reports 'Confirmed'
-> CommTouch Anti Spam Daemon
Sophos seems to use Cyren (ex CommTouch) as anti-spam check.
I've already checked that our ip is not black listed.
Is there a way to see why Cyren marks us as spam.
I have the X-CTCH-RefID of one of those mails.
We had the same problems 3 weeks ago and it disappeared after a couple of days (after a Sophos update one of the admins told me then).
Thanks,
Kris
