I was wondering if someone could shed some light, currently i have zimbra server around 100 mailboxes,
so far zimbra is great and all but its heavy on resources, the updates are a bit fragile and wanted to move to docker
which i came across mailcow which seems to have everything i need.
My question is for the migration would i just use imapsync? to send the mailboxes?
also im using proxmox email filter then it sends to zimbra, in this case would i be able to replicate the same scenario?
also i was reading that mailcow uses ActiveSync so able to configure similar to exchange on the mobile devices? instead of imap
