以下是一个简单的DNS查询MX记录的Python示例代码:
import dns.resolver
def query_mx_record(domain):
try:
answers = dns.resolver.resolve(domain, 'MX')
for rdata in answers:
print(f"Priority: {rdata.preference}, Mail Exchange: {rdata.exchange}")
except dns.resolver.NXDOMAIN:
print(f"The domain {domain} does not exist.")
except dns.resolver.NoAnswer:
print(f"The domain {domain} has no MX records.")
except dns.resolver.Timeout:
print(f"Query timed out for the domain {domain}.")
# 示例查询
query_mx_record('example.com')
