Hi,

I just converted my malserver from a Windows hmail server to Iredmail on Ubuntu.
Everything seems to work, except one little thing.

In Hmail I was using a failover MX server from junkmailfilter (http://www.junkemailfilter.com/spam/how_it_works.html).
When my server went down the failover server buffered to messages. When it was back online, the failover server forwarded the messages to my server.

In IRedmail the forwarded messages go back to sender with the message:
"550 5.7.1 Service unavailable; client [184.105.182.44] blocked using b.barracudacentral.org"

Is there a possibility to whitelist the ip range of the failover server? Or disable something? SPF?
How do I do this exactly? ... I'm a real newbie at this.

In this case, you can whitelist the IP address in /etc/postfix/postscreen_access.cidr.

Did as you suggusted. Now the sender does not get a bounced mail, but still the mails are blocked.

I think the problem is now SPF checking. Is there a way to whitelist also for this and everything else.

I.e. a general whitelist for this IP ?

Thanks
