[isf-wifidog] Validation Email problems

Hi Jeff,

I have had problems over the years with postfix and name resolution. Are
using your gateway/router as the dns server, this has caused me grief in the
past. I have found that they can resolve things like www.thisdomain.com and
mail.thisdomain.com but can't resolve using thisdomain.com (all that postfix
has to work with).

The fix - find some external dns servers from your isp and add them to the
/etc/resolv.conf ... you have to add them on separate lines, i.e.


Don't forget to restart the network...reboot or /etc/init.d/networking

Hope this helps

  Subject: [isf-wifidog] Validation Email problems

  We at Montérégie Sans Fil (http://www.monteregiesansfil.org) (MSF) are
having some startup problems - mainly with new subscribers not receiving the
validation email.

  If I look at the (very short) user management page at
http://auth.monteregiesansfil.org, I see that fully one-third are still in
validation state, meaning the portal closed before they picked up their
validation email.

  If I look at the (very long) user management page at
http://auth.ilesansfil.org, I see about the same ratio for recent

  Concerning the MSF registrations, we the technical support group are at
our wits' end trying to figure out why the validation email works for some
and not for others. We have tried creating new userids for ourselves using
different accounts (gmail, hotmail, yahoo), and sometimes the validation
email is received, sometimes not. There seems no rhyme or reason to the
successes and failures.

  My questions are:

  1) Is this a common experience among WiFiDog users?
  2) What can we check in our network setup that might be causing this
seemingly-random problem?
  3) How can we monitor the validation process on our auth server, to see if
the validation emails are being sent, or if they are in the mail queue?

  Any help or suggestions would be GREATLY appreciated!

  - Jeff
