    Change spam report sender name

    Thank you tom, I see that you can indeed put in the full email address as you wish to show up. I was simply under the assumption that the FROM field option allowed me to change the mail address before the @ sign. However it allows you to change the entire email address, understood. Thank you...

    Change spam report sender name

    Sorry to dig up an old thread, but my question was similar. My From shows up as: Mailgate@mailgate.domain.tld How can I just have it show up as, "Mailgate@domain.tld"? Is that a postfix setting?

    Intel IOMMU - Dell Poweredge 1950iii

    I've been looking through the Proxmox forums for the past two days in regards to enabling IOMMU on my server. I am trying to enable IOMMU in order to do a PCI passthrough of my Intel 3650 NIC. I have another Dell Poweredge R510 with the the same NIC and version of Proxmox with no issues. Here...

    .tmp: Cannot open: Permission denied

    Hey Martino, Login through terminal or SSH onto your Proxmox server. Make sure your USB drive mount has the correct permissions. I encountered the same issues and realized the permissions were only set to 700. So this was my setup, my USB drives main partition was sde1, ( you can find out...

    Best Practices for Environment Upgrade

    Thank you sir. I had in fact read that setting up ZFS ontop of a HW RAID is a bad idea. That is fine, although replication would have been sweet, I am more than content being able to pass VMs and LXCs around via the PBS. Thank you again for your input.

    451 4.3.0 Error: Queue File Write Error

    Yeah cant figure it out, my guess is that our domain fell victim to some sort of NDR spoofing attack? I'm just baffled cause there's no "from" address, and its just coming straight from my Exchange server by the hordes. I tried setting up some filter rules for it by matching the field "to" to...

    451 4.3.0 Error: Queue File Write Error

    I take that back, I still have no idea wtf is happening. My Mailgate is over 100% CPU utilization and consuming all its RAM as well. My exchange server is dumping all this to my mailgateway and I dont know why or what or how. Mar 23 15:24:50 mailgate postfix/smtpd[24823]: connect from...

    451 4.3.0 Error: Queue File Write Error

    So I looked into the nature of the error more and run into this Postfix documentation: https://www.postfix.org/SMTPD_PROXY_README.html Seems the error and the mysterious "supplier@mail.domain.tld" had to do with Before Queue Filtering. I recalled that I had also enabled that setting as of...

    I am extremely perplexed by these error notifications I am receiving from my Mailgateway. This email address (supplier@mail.domain.tld), which does not exist, is involved somehow and I am confused where it is coming from, and why I keep finding it in all domains outgoing and incoming email...

    Relaying from External Sources

    You definitely shouldn't have it open to the world. Ensure your NAT/Port-Forwarding rule is configured so that it only permits traffic on port 26 from your external mail server. If any other address tries to send mail or traffic to port 26, your firewall should drop those packets/traffic.
