I work with another open source project and they gave me an alias to use with their organization. I can successfully receive email from the alias to my local email.
However I would like to send email as the alias. If I just sent it up in my mail client, when I try to send email, I get:
The reported error was “RCPT TO <alias> failed: <mymail>: Sender address rejected: not owned by user <mymail>”.
Workaround: I create a local alias in MIAB admin for the alias to my email. Great! I can now send email as the alias.
Except if I want to email someone else at the project. Then I get:
Recipient address rejected: User unknown in virtual mailbox table
Which I assume means that the mail server in my MIAM installation is trying to find a local account for them and it fails
So what is a better workaround? I don’t mind editing config files but I really don’t know much about mail servers so I don’t know where to begin.
