Hi everyone, I tried checking the archives so I apologize if I overlooked the answer. I have 2 questions, based on the log snippet below.Note that I modified my master.cf to show the port number instead of the word "submission" as it makes it easier for me to visualize the flow of email. It's obvious the user is failing authentication, and from what I've read the word: UGFzc3dvcmQ6 is literally "Password:" My question is, does that mean postfix is literally receiving that word, or is it obfuscating the real password that was attempted? Anything else for tips or advice is also appreciated.
