No email notifications are being sent out to any user be it for node creation, update or new comment etc. Default setting is that users are auto subscribed for notifications. Cron is running every 10 mins and I dont see any errors etc in log entries. Infact, I dont see any mention of notification or mails etc in the log entries which makes me wonder if the modules are installed correctly or not.

I tried to send test mails to users using their contact form and they are receiving those mails. But for some reason they are not receiving any notification mails.

I have drupal 6.20 installed on a dedicated webserver with the following specs

MySQL database 5.0.45
PHP 5.1.6
Web server Apache/2.2.3 (Red Hat)

Following Modules are enabled for sending notifications to users
Messaging 6.x-2.3
Messaging Mime Mail 6.x-2.3
Simple Mail 6.x-2.3
Simple messaging
Content Notifications 6.x-2.3
Notifications 6.x-2.3
Notifications Autosubscribe 6.x-2.3
Notifications Lite 6.x-2.3
Notifications UI 6.x-2.3
Notifications Views 6.x-2.3
Taxonomy Notifications 6.x-2.3
Organic groups 6.x-2.1
Organic groups access control 6.x-2.1
Organic Groups Notifications
Organic groups Views integration 6.x-2.1

Any suggestions on how to debug?

I've the same issue. The notifications using lite API, aren't send.
I think you will be waiting a long time for a response.

Please check #857482: Drop Notifications Lite module

I'm having the same issue as well

UPDATE: Possible solution

I went to the Administer > Site Configuration > Input formats, and I changed the default message format to Plain Text.

I then went to Messaging & Notifications > Messaging Settings > Send Methods, and verified that it was in plain text. I then did a couple tests and i got email notifications to my OGs. I got the tip here: http://drupal.org/node/252619. It may have been a problem with a plain text emailer trying to send out filtered HTML.

I believe this is caused by #1088020: send_interval is set to NULL when sending mails to all members of a group
