Gerald, I am planning a similar migration here, from Zarafa to SOGo. What I am doing is using an extra field on AD to filter users on sogo, so my postfix filter is something like that:
query_filter = (&(|(mail=%s)(othermailbox=%s))(c=1)) and I manually set c=1 for users already migrated to sogo. Users still on zarafa won't be found by my postfix. Then my transport file looks like that: [email protected] dovecot: example.com relay:[mail.zarafa.example.com] But in my case, zarafa is the MX (it's also postfix). -----Mensagem original----- De:Gerald Brandt <[email protected]> Enviado:Qui 01/10/2015 07:34 Assunto:Re: [SOGo] Incremental Migration Para:[email protected]; On 2015-09-30 04:36 PM, Infoo Matic wrote: > I would use postfix as my main server.

If it's internal email, it never seems to leave the system. Thanks, Gerald > > > -- [email protected] https://inverse.ca/sogo/lists -- [email protected] https://inverse.ca/sogo/lists
