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 =
smtp-relay.gmail.com:587" (at leas

Hello,
We have a voicemail system that emails the voice messages to the
users. It uses the Caller ID info in the Display Name area of the

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

voicemail system. All works fine except for posts that get bounced as

We're getting many lost connections from our new phone systems
voicemail to email service. The actual voicemails and other emails
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
connections. The phone system is an
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
