python re.search() is not matching the pattern,

python 2.7.3: I'm sure I'm missing something simple but not able to figure it out I have a text file and I am reading file line by line:

dnsfile = open(self.logfile, "r")
        for i, line in enumerate(dnsfile):

each line i am matching for some pattern:

match = re.search(r'(.*mail.*?) (.*) NS (.*)', line)
if match:
    print  "Matched"
else:
    print "No match"

I am getting "No match" for all in file I have following lines which i am looking :

outlook.mail.com.               269     NS      ns1.msft.net.
mailxyz.com.          123695  NS      adns1.apple.com

I am trying same pattern and line on http://pythex.org/ and its matching but not with this code.

You have tabs, not spaces, in your DNS file. Try this:

match = re.search(r'(.*mail.*?)\s+(.*)\s+NS\s+(.*)', line)
