Transition from MailMan.MxLookup to Dns.Query

Provides instructions for replacing deprecated MxLookup method calls with the Chilkat Dns class. CkPython

import sys
import chilkat

success = False

mailman = chilkat.CkMailMan()

# ...
# ...

emailAddr = "joe@example.com"

# ------------------------------------------------------------------------
# The MxLookup method is deprecated:

domain = mailman.mxLookup(emailAddr)
if (mailman.get_LastMethodSuccess() == False):
    print(mailman.lastErrorText())
    sys.exit()

# ------------------------------------------------------------------------
# Do the equivalent using the Chilkat DNS class

dns = chilkat.CkDns()

json = chilkat.CkJsonObject()

# This gets all MX domains for an email address.  (Typically one domain.)
# The preferred domain will be at index 0 (see below).
success = dns.Query("MX",emailAddr,json)
if (success == False):
    print(dns.lastErrorText())
    sys.exit()

i = 0
count_i = json.SizeOfArray("answer.mx")
while i < count_i :
    json.put_I(i)
    domain = json.stringOf("answer.mx[i].domain")
    print(domain)
    i = i + 1
