Aliases and domain-side wildcards

A quick heads up, if you create an alias like [email protected]* = [email protected], MDaemon will follow that instruction literally, and alias [email protected] every single domain whether or not you host it.

If one of your users were to try emailing [email protected] the mail would hit [email protected]

Instead of using [email protected]* you should use the $LOCALDOMAIN$ macro instead. Create an alias of [email protected]$LOCALDOMAIN$ = [email protected] to route the pos[email protected] address for each of your domains, but no non-local domains, to your local administrator bob.

  1. Is it possible to create a domain alias? I say this because I have a company that has changed domain, and so I would like to alias all mails (the addresses are the same) to another domain..

    i.e. [email protected] –> [email protected]

    so *.domain1.com to *.domain2.com

  2. Francesco, yes this is possible. Create an alias of *@olddomain.example = *@newdomain.example.

    You might want to make sure that the option to relay for aliases containing foreign domains is disabled though, this option can cause some side effects in this configuration.

  3. Claudio, you can modify alias.dat manually if needed but it’s easier to just use MDaemon’s alias editor, you can enter these aliases directly in MDaemon’s alias editor.

  4. this is a bit old but though I add to it, I’m using Mdaemon 13.x and found out you also needed to make sure the domains been forwarded are also in your main domain list.
