If you uncheck "Enable outbound IP binding" and "This domain recognizes only connections made to these IPs" for both domains, what happens? Does the OS choose the desired IP? It's very suspicious ...

Hi Arron, Thank you for your feedback. Currently we enable back our Anti-Virus function, but disable ClamAV scanning function. So far we have not experienced the same problem.  

@Arron Can i send log (would it be only smtp out one for 31st?) to your email adress? I'll ask spamhaus for a copy but getting response might take a while. At the moment our network technician i...

Lets look at the last 12 hours of your MDaemon logs and see if we can find anything.   If MDaemon is processing the messages and generating the NDR, it will be shown in the MDaemon logs.&...

I'm not seeing anything wrong with the versions of the Ikarus files or the config files for either AV engine.  If you process the message again through MDaemon, does it scan correctly? Make s...

@Arron I've got more details from spamhaus, but still can't wrap my head around it: does it mean the rejections are being sent back with wrong HELO? As of 12 hours after your request. This is st...

Understood.  Thank you for your help.

You can change the IP that is used for the logging by going to Setup / Domain Manager / Select the Domain / Host name & IP.  In the IPv4 field enter the IP address you would like to be use...

Before they sent last test we had rdns set incorrectly, could it be reason behind it?  According to the report from spamhaus a server is announcing itself as localhost.localdomain.  It...

We have only one server running - mdaemon, port 25 is directed to this local server only on firewall. Before they sent last test we had rdns set incorrectly, could it be reason behind it?  Th...

Its not normal, our server rejected the message because your IP is listed on spamhaus.  I've added the domain-test@mdaemon.com address to the DNS-BL allow list.   I can see in our l...

I am not familiar with adding a "Web Reference", however, the XMLAPI uses Basic authentication, always. First, unrelated to the 401 you are receiving, is that the content-type header on any post o...

Have you looked at IIS Not for a while. Quite a few MD versions ago we were looking into that, but (don't really remember why) decided not to implement.Looking into Web Server Exclusions page, I...

So far I have been unable to reproduce the issue.   Are you using the 32 or 64 bit version of MDaemon? What is the version of C:\MDaemon\SecurityPlus\Ikarus\scan.server\bin\scanserver_w...

Yes, it could be the firewall or another SMTP server accepting inbound connections.  What do you get if you telnet to your IP address from the internet on port 25?   telnet $IP$ 25 ...

You are correct, it would not change anything in regards to the requests being logged by your firewall, but it will make your server more secure. Even if those requests are allowed through your fir...

Have you contacted uribl?   There are some tests you can run here that might help figure out what is going on, https://uribl.com/about.shtml. You could also disable the lookups in spama...

since two weeks ago spamhaus kept on putting our IP address on the CSS blacklist - we've had few thing to fix from the guideline so we delisted ourselves few times after checking all the requiremen...
