jabacz Hello, I’m trying to migrate form Exchange to Mooo In the pilot I encountered a problem I have mailbox user@domain.xxx This mailbox is supposed to be target for multiple aliases like firstname.surname@otherdomain.yyy both domains are registered in Mooo Mailbox alias created for firstname.surname@otherdomain.yyy -> user@domain.xxx When testing email comes, Mooo responds with “ No user at this address” What am I missing? Thanks
esackbauer Did you activate one of the relay options for that domain? If yes, than you should disable it.
esackbauer Without properly describing what you have set up, and what you want to do, we can only guess. Which domain is the exchange server? Send connectors in Exchange, where are they pointing to? Where are the MX records pointing to?
jabacz Maybe I wrote it unclear. There is no relation to Exchange other, than Moo should replace it. Lets say (testing names) Mailbox is hoho@hoho.cz It should receive email for adam.great@business.eu domains hoho.cz and business.eu are registered at Moo At the mail Alias page is record created: mail for adam.great@business.eu goes to hoho@hoho.cz The server can receive mail for hoho@hoho.cz Mailbox is accessible through SoGo and IMAP When testing mail goes to adam.great@business.eu the response is “No user at this address” Keep in mind: this is lab setup with no connection to the old Exchange. There are other testing servers and isolated testing DNS. The error can be evoked with console access to SMTP port 25 …. yes, I can write SMTP commands like MAIL FROM: and RCPT TO: manually :-)
esackbauer I guess you need to look at the rspamd and postfix logs. Could maybe also be a DNS problem. Unbound container is not using “isolated testing DNS” unless you tell him to do so. So maybe the external DNS servers have a MX record for business.eu still pointing somewhere else.
jabacz Maybe we are touching the wrong side :-) Could you write step-by-step instruction to setup my required environment at fresh Moo server? Suppose hoho.cz domain and hoho@hoho.cz user/mailbox set and working as expected. Thanks
