What did you mean, that user John has [email protected], [email protected] and [email protected] ? If so, I have made so. It would be better to do with the latest Samba4 and Openchange verions, but I did so via proxyAddresses since I have authorization of all installed components by built-in Samba4 LDAP, that is AD like LDAP server.
Some of users has two or three mail aliases. And it works. -- [email protected] https://inverse.ca/sogo/lists
