Good day. AT our head office we have 3 post offices and one MTA. 2 of the post offices are receiving the internal comms from the DL. One is not.
The Internal comms DL is on another post office at head office, under the same MTA.

Could somebody please give me some ideas? I went through all the settings through the admin console. I recently took over and I am not sure if the previous admin did this, or if there is something else wrong.

Ideas would be appreciated.

If I try to Synchronize the group it fails. I have tried running rebuilds on the MTA and POA's.
