sync emails between two servers

Xxyphos · Aug 9, 2021

Hello everyone, I find myself needing to sync email between a local mailcow server and an offsite non mailcow server.

The way I have my system configured is that my main email server is hosted using mailcow on my own network. I also have a secondary email server hosted by MXroute as backup for whenever I have power outage or my ISP decides to give trouble. I want to be able to have mailcow connect to mxroute server and download any emails for user x,y,z. It would be a one way sync (download email only)

I noticed mailcow has Sync jobs options but I am too unfamiliar with it. Would this be able to do what I want? If so is there any options that I must specify for it to work.

Hi, yes, that’s no problem if you use sync jobs on your backup server.

None

You have to create a sync job for every mailbox you want to sync. You have to create the domains and mailboxes before creating the sync job if it’s a plain mailcow.
