We're getting many lost connections from our new phone systems

send OK but we also see constant hits anywhere from every minute to 8
minutes on the mail server from the phone system that are lost

Thank you!
I think I found the issue - the new phone system was installed
configured on vlan 200, but the smtp settings were copied over from
the old system which was on the default vlan 1 so what was happening
was that the voicemail system was contacting the smtp server via the
vlan 1 address (ro
You could run Postfix in a container (LXC) on the host. It would have

A problem occurs when the Caller ID contains a comma which causes the

Hello,
I have a simple relay for sending emails from internal scanners and a
voicemail system. All works fine except for posts that get bounced as
the bounce notifications somehow fail both SPF and DKIM tests.
The only (seemingly significant) differences I can find in the headers

The remote servers reject, or place in spam, bounced and NDR's from
the relay, due to a strict DMARC policy.

I don't think you can use gmail as a relay host unless Google is
handling your domain's mail service (a GSuite account - not @gmail.com
addresses). They have instructions for setting this up and the proper
relay host once you've done the admin work is "relayhost =

Looks like a normal reject of a consumer based endpoint (IP address).
Pretty common, most major services will reject email from such addressess.
When you're using Thunderbird you're most likely authenticating before
sending which is not the case with Postfix.
