Looks like a found a solution in "Unix & Linux System Administration Handbook": main.cf needs two lines (I just had one - virtual_alias_maps): virtual_alias_domains = $virtual_alias_maps virtual_alias_maps = hash:/etc/postfix/virtual John Schmerold Katy Computer Systems, Inc...

OK, thanks - that's more complicated. I will sit tight until you have time to approve my postings.

Not 100% certain, but try: sudo pmgconfig sync postmap /etc/postfix/virtual systemctl restart postfix

I posted a reply to the PMG forum, it's marked "This message is awaiting moderator approval" In many cases I can edit my posting to avoid wasting a moderator's time. What criteria does Xenforo use to delay posting?

I am working on a similar project, I am getting a recipient rejected message ( CLIENT: 450 4.7.1 : Recipient address rejected: Service is unavailable). How do I get PMG to recognize virtual addresses found in /etc/postfix/virtual ? Here is what I did, perhaps I took a wrong turn: create...

Our mail gateway is configured using KVM technology. I am going to switch it to a PVE container. Is there a command to deactivate the mail gateway's subscription before migration?

What is everyone using to disarm various html payloads such as form, IFrame, object codebase, script and other phishing tags? Mailscanner.info does a nice job of this - perhaps it could be integrated with PMG.

Another option: PowerDNS Install: apt-get install pdns-recursor -y Edit allow-from: nano /etc/powerdns/recursor.conf Restart things: /etc/init.d/pdns-recursor restart Set local recursor: nano /etc/resolv.conf Restart network: systemctl restart networking Test things: dig google.com

How do I mark the thread "Solved"? I spent a bit of time on the Xenforo site -no joy... I am looking forward to getting my "Proxmox Subscriber" trophy :)

Make sure you tell cPanel about PMG on /scripts6/editremoteipslist the issue is documented here: https://confluence2.cpanel.net/display/82Docs/Configure+Remote+Service+IPs I also whitelist PMG's address on /scripts2/displayeximconfforedit as documented here...

My primary concern is the elimination of backscatter. I don't want PMG to accept a message for joeblow@bigcompany.com, forward that message to Office365, then have that message returned to sender in a separate transaction. It seems PMG handles this situation brilliantly. The first time Joe gets...

In cPanel WHM, you want to go to the Exim Configuration Manager & search for "Smarthost support", select the second bullet, in the box input: * pmg.AmithKumar.com That will send all outbound email to the PMG hosted on pmg.AmithKumar.com, by default it will use port 25. Based on...

In a perfect world, PMG would use the LDAP directory for: - receiver verification - receiver forwards (sally@bigcompany.com ==> sallyworksfromhome@aol.com) - group forwards (tech@bigcompany.com==> joe@bigcompany.com, sam@bigcompany.com, sally@bigcompany.com) - provide quarantine interface...

PMG v6 is based on Buster, does that eliminate the need for "stretch-backports" ? Sorry - I am a complete Debian newbie -- I have been using Centos as long as I can remember, it's going to take some time before I get comfortable with the whole apt-get thing.

PMG's TLS support uses a self-signed TLS certificate. Is there a way to auto generate & update a Let's encrypt certificate? Another option: We have a wildcard certificate for our domain, so I could use that if we'd get better results. I am mostly concerned about TLS support for Postfix, but...

When installing Proxmox mail gateway in a virtual environment, is it better to install on VE vs vmware -- or does it work equally well in either environment. We are a vmware shop, open to trying new things.
