Why
I cannot see notification mail from CCKM SMTP? I am sure my email address and SMTP
server configuration are correct.

In
order to reduce email, CCKM SMTP will send a mail by:

1.
Accumulate 100 logs and send a mail.

or

2.
If no more than 100 logs in 30 mins, one mail will be sent.

or

3.
Send a mail immediately when an “Error” level log occurs.
