[Mailman-Users] Server skips Mailman - more II
Hi again. I'm not sure if it makes any difference, but... mailman should resolve a subdomain. I have a contact.enterprise.com subdomain. And I don't have any list.contact.enterprise.com. I mean, Mailman should resolve directly the contact.enterprise.com I have a MX record in enterprise.com DNS server pointing to contact.enterprise.com. And 'contact' machine is where the postfix/mailman is installed. I still stuck on User unknown in virtual mailbox table. And I can't imagine why this error doesn't happen when I'm using an account (even from another domain) hosted at the same server/machine/postfix.

I have a contact.enterprise.com subdomain. And I don't have any list.contact.enterprise.com. Actually, even the name server at ns1.enterprise.com has no A or MX records for either domain, contact.enterprise.com or lists.contact.enterprise.com. That raises the issue of how external mail even gets far enough to get a Recipient address rejected: User unknown in virtual mailbox table error.

I still stuck on User unknown in virtual mailbox table. And I can't imagine why this error doesn't happen when I'm using an account (even from another domain) hosted at the same server/machine/postfix. If I send mail to local_addr...@lists.contact.enterprise.com, there MUST be an MX or an A record in DNS for lists.contact.enterprise.com, or my MTA doesn't know where to attempt to deliver that mail. It doesn't 'fall back' to contact.enterprise.com or enterprise.com; it just gives up. All this has to work before the message will even get to the server that Mailman is running on. If the Mailman/Postfix server is contact.enterprise.com, you need an A record for contact.enterprise.com and an MX record for lists.contact.enterprise.com giving contact.enterprise.com as the target. Otherwise, the mail will never get to your server. Alternatively, you can have just an A record for lists.contact.enterprise.com giving the IP address of the server. You don't appear to have any of these DNS records. -- Mark Sapiro m...@msapiro.netThe highway is for gamblers, San Francisco Bay Area, Californiabetter use your sense - B.

Mailman is not a DNS server. It doesn't 'resolve' domains. Yes, I know. I have a MX record in enterprise.com DNS server pointing to contact.enterprise.com. Not that I can see? My God! Sorry, I haven't said that the domain 'contact.enterprise.com' is only an example in this message.

Please don't use real (or even potentially real) domains when you are trying to obfuscate your own domains. You have three, and ONLY three choices: 1) Use the real domains. In most cases, this is a good choice as it allow people to do things like check your DNS, your rDNS, etc. 2) Use example.com example.org or example.net 3) use a made up domain ending in a made-up non-existing tld. For example, I would have said I have a contract.enterprise.tld subdomain. tld stands for top-level domain and is not a valid tld. If you go with #3 you have to be POSITIVE that the tld you use is not used, potentially used, or under review to be added. .xxx is a terrible choice for these reasons. .tld .moc .example are all reasonable choices In the example you gave, enterprise.com is a domain name for Enterprise Rent a Car. -- I believe you can joke about anything. -- George Carlin -- Mailman-Users mailing list Mailman-Users@python.org http://mail.python.org/mailman/listinfo/mailman-users Mailman FAQ: http://wiki.list.org/x/AgA3 Security Policy: http://wiki.list.org/x/QIA9 Searchable Archives: http://www.mail-archive.com/mailman-users%40python.org/ Unsubscribe: http://mail.python.org/mailman/options/mailman-users/archive%40jab.org
