The reports are always sent as bounces (with an empty envelope from) to not generate NDRs for the reports:
https://git.proxmox.com/?p=pmg-api....0c74bd27c3a4bd751561032e1a04ef52177db53#l1264

I think you need to allow your PMG's ip in your gsuite settings - as described in the link from your logs:
https://support.google.com/a/answer...il-relay-denied,invalid-credentials-for-relay

I hope this helps!

our pmg out using NAT from firewall and the IP address pubblic is authorized to receive emails, in fact is our pmg using this nat address to send to our gsuite domain in google.
my question is from=<> ..... how can i change this to set for example root@mydomain.tld (registered on gsuite) ?

as said - this is hardcoded to not generate NDRs - however I'd assume that google will have a way to configure that you are ok with receiving bounces (mails with empty envelope address) from a particular IP...
(mail does rely on sending out mails with empty from address for its operation (e.g. to notify you that a mail could not be delivered))

 

[emper0r]

sorry but i don't sitll understand, how can i get the report daily then ?

* either pick a different e-mail for your admin e-mail
or
* ask google support how to configure your settings to allow these e-mails

 

[emper0r]

let's do different.. the line under Utils.pm can I changed to set my email from ???

https://git.proxmox.com/?p=pmg-api....0c74bd27c3a4bd751561032e1a04ef52177db53#l1265

PMG::Utils::reinject_mail ($top, '<THIS is the email i want to set ???>', [$receiver], undef, $data->{fqdn});

have to restart any services or just work after modify it ???

 

[Stoiko Ivanov]

Yes - but this would get replaced again on every update ...
as said I think you need to configure your receiving server (gmail) to accept those mails with empty envelope from

 

[emper0r]

don't worry, I take note about any modification did it on pmg to after update set again....
