Our mail system is setup such that outlook forwards mails to the wingate server which then forwards it out. Some of the local mails get resolved locally while others are sent to our mail hosting server.
This system was working fine till a few days ago. Now the mails whose domain mains we have registered in our domains tab but which dont have local mailboxes are not being delivered.
I read the logs. The SMTP server log says sent. There is no record of it in the SMTP delivery service.
Please help with this regards.
