Hi guys
I have an MiaB installation that worked fine during a week. But now I can’t send or receive mail.
What happened?
I pasted the last few lines of the mail.err log here: http://snippeter.krizdelogi.be/public.php?id=179
Thanks in advance everyone!

EDIT: //snippeter.krizdelogi.be/public.php?id=180 this is a mail I received from mailer-deamon (I don’t understand why there are other mail adresses that don’t have anything to do with my domains)

Looks like you are missing a DNS entry.
Also Out: 451 4.3.0 Error: queue file write error
Means you have a permissions issue in the server.
I checked the DNS entries and all seem correct. Only the web entry is not set because I don’t want MiaB to handle my web requests.
Okay, I got it working again, but now I see my mail gets sent or received very slowly, so I had a look at mail.log and was surprised to see some unusual traffic. How can I block this?

What are these domains exactly doing on my server?
Thanks in advance

Ok. I just restarted everything over again. Hoping that everything becomes secure
Is your domain krizdelogi.be or delogi.be ?? Or are you hosting mail for both domains on your box?
I’m hosting both domains. Also dlds.be and vanparysenhof.eu
