## SYNTAX08: MX name must have a valid hostname
|
|
|
|
### Test case identifier
|
|
**SYNTAX08** The MX record name must be a valid hostname
|
|
|
|
### Objective
|
|
|
|
The MX record names used for delivering mail for a domain name address
|
|
must be valid hostnames according to the rules defined in
|
|
[RFC 952](https://datatracker.ietf.org/doc/html/rfc952),
|
|
in section 2.1 in [RFC 1123](https://datatracker.ietf.org/doc/html/rfc1123#section-2.1),
|
|
section 11 in [RFC 2182](https://datatracker.ietf.org/doc/html/rfc2181#section-11) and
|
|
section 2 and 5 in [RFC 3696](https://datatracker.ietf.org/doc/html/rfc3696#section-2).
|
|
Newer RFCs may override some rules defined in earlier documents. The MX
|
|
records use of "Domain Names" is described in section 2.3.5 of
|
|
[RFC 5321](https://datatracker.ietf.org/doc/html/rfc5321#section-2.3.5).
|
|
|
|
### Inputs
|
|
|
|
The hostnames to be tested. The hostnames comes from looking up the MX record
|
|
for the domain being tested.
|
|
|
|
### Ordered description of steps to be taken to execute the test case
|
|
|
|
1. Query for the MX record of the domain name.
|
|
2. For each hostname of the MX records found:
|
|
3. If any label in the hostname does not contain a-z or 0-9 this test case
|
|
fails.
|
|
4. If any label of the hostname is longer than 63 characters, this test case
|
|
fails.
|
|
5. If the hostname is longer than 255 characters including separators, this
|
|
test case fails.
|
|
6. If the rightmost label (the TLD) contains only digits, this test case
|
|
fails.
|
|
7. If there is a hyphen ('-') in position 3 and 4 of the label, and the prefix
|
|
is not xn (used for internationalization), this test case fails.
|
|
|
|
### Outcome(s)
|
|
|
|
If any of the steps 3 to 7 in the ordered description of this test case fails,
|
|
the whole test case fails.
|
|
|
|
### Special procedural requirements
|
|
|
|
None.
|
|
|
|
### Intercase dependencies
|
|
|
|
None.
