Hello everyone! I have a doubt about mailman in ISPConfig. I created a test list in ISPConfig, enter the mailman administrator and add some post members. Priate I attempt to send an email to the list from my thunderbird I get a message saying that the account does not exist [email protected]. Reading this article it seems that there should be a file called virtusertable in the folder / etc / postfix but this file is not. Article also shows that an alias be created to mailing list but does not appear. What am I doing wrong? Mi ISPConfig version is 188.8.131.52p3 I remain attentive to your comments. Note: When I run the command list_members and list_lists, the correct information is displayed.
