Dear Folks, I need a custom SMTP authentication solution. There is a database that contains about 5000 user authentication data. Now we want to provide SMTP service for these users with same credentials. I know I can create a view-only user in database server and connect to it via SASL - MYSQL and check user authenticity; But it is a little dirty affair. I'm looking forward finding a way that authenticates users via web service or any other authentication method that is faster and stable than mysql - sasl. (Performance is very important). Do you have any idea or recommendations for me? Thanks in advance
