limiting emails from smtpappender (log4Net)

I am looking for a way to limit SmtpAppender to limit number of emails sent in case of same error is occurred multiple times in a defined time span.

I don't know if it is even possible, any help will be appreciated

From stackoverflow

• You could always extend SmtpAppender to implement the functionality you need.

• I understand, but it will be great if you can shed some light on how this can be achieved.

• I have not tried this extended SMTP appender, but it seems to be be what you need.
