If they use the submission port 587 it will not check for any rbl. Thats the basic idea of the submission port.

Yes, and yes. In case 1) I recommend to make qmail all mails forwarding to the provider's regular SMTP server. Different users and different situations (i.e. roaming users) makes this nearly impossible. In case 2) your users should better use the submission port 587 with authentication to send mails. They are, I'm still getting this issue. The problem is in case 1) that even when you whitelist those IP-Addresses, other many other recipients will not be able to receive those mail, because many providers are using the spamhouse blacklists... Easiest is how do I just disable this 'check/scan on SMTP' from qmail? I tried already to edit the /var./qmail/control/blacklists file and remove spamhaus, but that made no difference. How do I disable this feature..? --- Sun-Tzu Those who make peaceful revolution impossible, will make violent revolution inevitable.
