Cisco ESA - SMTP authentication best practice

[galin.gospodinov]

Hello community, 

what is the best practice to use SMTP authentication ? If we have smtp authentication on mail server is it a good practice to switch it to Cisco ESA ? I can`t find, what is the mail flow when user is using smtp authentication on Cisco ESA to send a mail. Where the information for send emails are stored ?

Thank you!
