When i delete all entries from Banned IPs, Banned Names and banned emails then new users get confirmation email. if there are entries in Banned IPs, Banned Names and banned emails then forum treat every user as spam/BOT and did not send confirmation email. you can see there are some entries

The email sending has nothing to do with the banned name/ip/email feature. This looks like more of an issue with the email provider you are using. Is this issue also occurring with a different email provider?

i am using SMTP Email and you can check its setting.

how can i change email provider? how can i check which email provider i am using?

Sorry but i don't know why your user names or ip adresses are listed in the database. The problem is everyone can submit data to the database. But YAF is not repsonsible of that. You could try StopForumSpam instead. We use it here in the Support Forum. and it seems to work much better.

Kindly tell me about email issue. That confirmation emails are not sending and sometimes other emails are also not sent to users. what setting i should change to fix this issue.

Sorry i can't help you much about the email issue. The only thing you could try is to set the credentials for the email account in the mail.config..

<smtp deliveryMethod="Network" from="forumadmin@yourdomain.com">
	<network host="yourdomain.com" port="25" password="username" userName="password" />
</smtp>

As per your instruction i change my BOT setting to StopForumSpam and also set it to disable but it is again taking all user as bot/spam.

please check latest event log

Banned Name list is creating this issue. Exact name is not in banned name list but i deleted all entries of banned name list and now registration process is working fine and i got confirmation email.

i think banned name logic is not accurate in YAF forums.

Well at least here it works without issue. can you export the list of banned names and attach the txt file here?!
