Re: [Bug 658795] Re: postfix gets confused with non-alphanumeric local hostname
RFC 2119 (IIRC, I don't have web access to check) generally discourages TLD validation, but calls out all numeric TLDs as an exception that should be checked. So in general, I agree about TLD validation, but all numeric is an exception. I agree that there is an issue, but not in the postfix package. Its input validation is catching the results of input validation failures elsewhere in the system. I've proposed looking at this more systematically in the next development cycle. -- postfix gets confused with non-alphanumeric local hostname https://bugs.launchpad.net/bugs/658795 You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to postfix in ubuntu. -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
[Bug 658795] Re: postfix gets confused with non-alphanumeric local hostname
It's a valid hostname (numeric sub-domains are allowed in DNS), but it's not a valid FQDN. However I'm not convinced that newaliases should fail like this. Shouldn't it just create an empty alias database? Should Postfix be policing which TLD's are valid? It seems like that should be up to the receiving MTA.

No. That isn't a valid hostname. All numeric TLDs aren't allowed. ** Changed in: postfix (Ubuntu) Status: Confirmed => Invalid -- postfix gets confused with non-alphanumeric local hostname https://bugs.launchpad.net/bugs/658795 You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to postfix in ubuntu. -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
