Today, we are proud to announce the availability of Proxmox Mail Gateway 6.2. Our email security platform comes with some interesting new features like the full support for before-queue filtering. E-mail that is not accepted remains in the responsibility of the remote SMTP client, quite useful for some organizations.

We have extended and re-implemented the pmg-log-tracker in Rust, including support for parsing and grouping logs in before-queue filtering mode.

The upgrade has followed the good design & throughput as always. It is fast processing and has a nice web interface. We had reservations about the virus scanning and blocking which may end up blocking legitimate emails in the previous edition.
We hope to use the Proxmox mail gateway into the future.

The gateway has enabled technology reviewer to manage all the mails thus ensuring no spams.

Good afternoon, I just upgraded mine from 6.1 to 6.2, now I can´t access the system (on port 8006) via web (only ssh).
Is the service down or dead?

Something to think about

# systemctl restart pmgproxy
Failed to restart pmgproxy.service: Unit pmgproxy.service is masked.
# systemctl status pmgproxy
● pmgproxy.service
Loaded: masked (Reason: Unit pmgproxy.service is masked.)
Active: inactive (dead)

Ok it seems that all of the pmg services are either masked or disabled
systemctl list-unit-files | grep pmg

pmg-smtp-filter.service masked
pmgbanner.service masked
pmgdaemon.service masked
pmgmirror.service masked
pmgnetcommit.service masked
pmgpolicy.service masked
pmgsync.service masked
pmgtunnel.service masked
dev-pmg-swap.swap generated
pmg-daily.timer masked
pmg-hourly.timer masked
pmgreport.timer masked
pmgspamreport.timer masked

So I tried to unmask the pmgproxy.service:
systemctl unmask pmgproxy.service

Not the smartest move, now the service has been uninstalled
systemctl revert pmgproxy.service - doesn´t work either

What is my next move here?
apt install proxmox-mailgateway ? (will all my configurations work?)

this sounds odd ..
what's the output of:
apt update
apt full-upgrade

if this indicates an error try
apt install -f

apt install proxmox-mailgateway ? (will all my configurations work?)
this should also work - and your configs should not be changed by it - in any case make sure to have a backup!
