The alias name is "pruebasalias" in fact. I obfuscate with "alias". I had an error, sorry.
$ postalias -s /etc/aliases | grep pruebasalias pruebasalias: aalberola, prueba owner-pruebasalias: user1 I forgot the "ownler-pruebasalias". I made a test and works well. I return "expand_owner_alias" to "no" also. Thank you very much, and Wietse sorry. My English is not good. I don't understand in the previous email. Sorry. Thanks for your time.

And the associated "owner-<alias>"? And DO NOT obfuscate the alias name to "alias" that's confusing. Use some other non-generic name if you must obfuscate at all. Example: $ postalias -s /etc/aliases | grep waldo owner-waldo: user3 waldo: user1, user2 And don't set "expand_owner_alias" to "yes", that's generally a bad idea. Leave it at the default value of "no". Do however make sure that the associated "owner-waldo@$myorigin" address routes to the local(8) delivery agent just like "waldo". -- Viktor.
