Send email on authentication

[Darm0ka]

Im making a ssh multiple factor authentication an I can easily send an email after authentication, what I want to know is if is possible to send an email in every step of authentication, if in sshd_config i have AuthenticationMethods publickey,password,keyboard-interactive, is possible send an email after publickey authentication, other email after password authentication and other after keyboard-interactive authentication? I think is possible using PAM but I dont know how to do it.

I found a solution based on ommail to send syslog messages via mail.
I put a script in /etc/rsyslog.d/ that trigger an email if a specific log matches my condition.
I also change in sshd_config LogLevel INFO to LogLevel VERBOSE
