Can't communicate with Google Apps email addresses
I am having a big problem with email on my server which is running Ubuntu and VestaCP.
I can send and receive emails fine unless I try sending an email to an address which is setup on Google Apps email. I also cannot receive emails from these addresses either. I can send and receive fine to @gmail.com emails however, its only those domains that are setup on google apps.
The log file says this everytime:
2016-09-28 12:26:21 H=mail-io0-f169.google.com [18.104.22.168] sender verify fail for <firstname.lastname@example.org>: Unrouteable address 2016-09-28 12:26:21 H=mail-io0-f169.google.com [22.214.171.124] F=<email@example.com> rejected RCPT <firstname.lastname@example.org>: Sender verify failed
any help would be greatly appreciated as I have spent all morning trying to figure it out.
