I ran

pmgqm status
Count Spamlevel Mail
1 10.00 xxxxxxx@xxxxxx.tech (external address)

pmgqm send --receiver xxxxxxx@xxxxxx.tech
returns nothing

pmgqm send -debug 1
returns nothing



I tcpdump either on the interfaces of the proxmox, nothing out there

..and also tcpdump on our firewall to be sure: same result ! nothing....



Can you help us out ?
Thanks !
Michael

hi,
what do you mean with :

(external address)

?
normally pmg should not send a spamreport to external email adresses?

also what is set as the spam report style (configuration -> spam detector -> quarantine -> user spamreport style)

Hi Dominik,

Thanks for reading us

PMG is installed front-end for testing purpose in our datacenter for our different customers.

Our customers have their own mailserver on prem' in their own infrastructure (and often are equipped with 2 different internet access)

Each customer have internally one mail server (mainly MS Exchange) with several domain names inside.

-> So the customer's MX are pointing to "our PMG", which relays to these different customer's infra (with LDAP verification for sure).
(with the use of a FQDN englobing the IP of their 2 different internet access)
This is the simpliest picture.



So, we have the MX of a domain called (example) "domain123.com" pointing to our PMG.

This "domain123.com" is configured in Configuration/Mail Proxy/ Relay Domains
Then in Configuration/Mail Proxy/ Transports, this domain is configured to send via SMTP/25 to the FQDN of the customer (which englobes their 2 different internet access)

The thing is, the email address of the customer for the domain we try to protect (let's say michael.jackson@domain123.com) does have different aliases in his Exchange Server
...and the primary one is not michael.jackson@domain123.com but michael.jackson@domain000.com (again, example)


So, in the Tracking Center, I can see emails for michael.jackson@domain123.com (accepted / rejected/ ...) which is fine
but in Administration / Spam Quarantine in the Email field, I see SPAMS in the list but the addresses are michael.jackson@domain000.com or michael.jackson@domain001.com, not michael.jackson@domain123.com

If I select a SPAM in the list of michael.jackson@domain000.com (example) , I can see Receiver the is correct: michael.jackson@domain123.com

So, in Administration / Spam Quarantin /Email Field, I do not have michael.jackson@domain123.com in the drop down list

Weird but that's it

Maybe should I configure the transport or relay domains with all the domains owned by our customers, but not (yet) protected by the PMG ?

Thanks again for your help, very appreciated
Michael

Hi,
I think that's the missing point

-> all the domains owned by our customer should be configured in the relay domains section (but not (yet) protected by the PMG)

yes you have to enter *all* domains into the relay domains for which you want to receive and forward mail
