i have migrated from exchange zu mdaemon the last two days.
If we send a message to an external client an a CC to an internal employee, the message comes back with "unknown user". The internal employee does not get the message.
If no user account exists for user8b78c79a and there is no alias, or mailing list (or something else in MDaemon to make the address valid), then the message is not to a valid local user and should be rejected.
It is not rejected in the last example because the session was from a trusted IP address.
Create an account for user8b78c79a by going to Accounts / Account Manager / New, are you then able to send to the user like you want?
But the employee only writes the CC address, which she always writes. Not this user user8b78c79a. Its a real name and adress
I'm not sure I understand. Are you saying that user8b78c79a is not the real account that the user is CCing mail to? If that is the case, please repeat all the steps above with the correct address. Does the account exist in MDaemon under Accounts / Account Manager?
Can you post log snippets that show what happens when the user tries to send to the real address? You can change the address in the log snippet if you want, it doesn't matter to me what the address is, I just need to see what MDaemon is doing.
Can you send to the account directly, instead of sending to it via CC?
That is very strange. I would also check the scretary's autocomplete and contact lists to make sure that a contact with user8b78c79a@domain.com as the email address does not exist. The easiest way to do this is to compose a new email on the secretary's computer and add Meyer to the recipient list. Then once added, check the real name and address in the To field to make sure it is the correct name and email address.
Then I'd check the sent items folder in Outlook to make sure previous messages were also sent to the correct address. If outlook shows the h.meyer@ address, then we'll need to see the MDaemon logs to figure out what is happening.
Zusammenfassung der Defekt-Warteschlange von MDaemon An Von Betreff Art Nachrichten-ID Datum USER8B78C79A@mxxhpartner.de muenchen@mxxpartner.de user from extern message to unknown local user <4ead01da31bf$c94640b0$5bd2c210$@mxxpartner.de> Mon, 18 Dec 2023 15:37:54 +0100 user8b78c79a@mxxpartner.de
I'd start by checking the inbound SMTP logs to see what IP address the messages are coming from. And then take a look at he email clients running on those IP addresses. Perhaps this was a valid address in Exchange that did not get moved over to MDaemon.
If you want MDaemon to start accepting the messages, create an account for the user. You can then login to webmail as that user and see what type of mail is being sent to the user and who is sending it.
