ISPConfig Mail rejects google.com relay

[FeraTechInc]

So I'm trying to set up the 5 e-mail accounts I have in ISPConfig.

ISPConfig Version: 2.2.23
Ubuntu Hardy Heron Perfect Setup

The mail.log error I get is:
NOQUEUE: reject: RCPT from rv-out-0506.google.com[209.85.198.238]

What I am trying to do is activate the send function so I can send my e-mails from gmail under that account except gmail requires verification of account.

I'am not sure if I understand you correctly. If you want to relay your emails trough a extrenal server, have a look here:

If you tried to send email to a gmail recipient, you should check that your server is not blacklisted and that the server IP has a correct reverse dns record.

Actually, it seems as though my server is rejecting ALL mail to every single one of my accounts with that error.

I am not using an external mail server.
