Hello,
I have a mail server "mx1" with this listening section : ------------------------------------------- listen on egress inet4 \ tls-require \ auth ------------------------------------------- I have also a server "test" and I would want to authenticate the user when sending an e-mail to the server "mx1" but I get an error : ------------------------------------------- test smtpd[9309]: f3880cf18b73253d mta error reason=AUTH rejected: 535 Authentication failed ------------------------------------------- "test" seems to connect properly on "mx1" but the error does occur on the user authentication. Because I can perfectly connect to "mx1" with a MUA like Thunderbird, it makes me think the error should be located on the opensmtpd "test" secrets file : ------------------------------------------- foo f...@mx1.example.org:password ------------------------------------------- The password is 40 digits long and looks like this : C>(3")GID~7B7%{~LIq_G*JdP6fTW*"[`G)<k?(G Can a special character be a problem in the password field ? If yes, how to deal with it ? Thanks for your suggestions.
