Authentication Error – Strange Solution

    I have been using this plugin for years and it is great. Recently no matter what I did it would not authenticate an email on a new website. I spent two day testing everything on both WordPress and cPanel and repeatedly making sure the settings and passwords were correct. You may think I am crazy but what fixed it was taking the % character out of the password. Maybe I am wrong but I tried not to change any other variables during my testing.

    Just thought I would pass this along. Take it with a grain of salt.

    Hi @yehudah, @tneville,

    I experienced the same issue. I used the following password on an smtp account: yT<3j}u%2D2>fByX

    That did not work at all even though I could login via thunderbird and other clients.

    It looks like the way the passwords are being stored or escaped is mangling the passwords somehow.

    The issue was resolved by limiting the password used to exclude these kind of “special” characters.

    Hi @redbullpeter,

    Did you test without the percent sign (%)? This is usually the one that causes the most trouble from my experience.

    I was the one who started this thread and then later I was using the program and completely forgot about it. I used a password for the email that had a % in the middle and fought with it trying to get it to work. I clicked on the help link in the program that came up that sends you to https://postmansmtp.com/incorrect-authentication-data/ where it suggest changing the ip address. I tried this also. Finally I remembered and went and changed the email password % to a #. Instantly it worked! So it is definitely the % that caused the problem.

    I love this program and am not putting it down at all but as a suggestion you might want to add a not to that help link page about not using the % in your passwords. This might save you and your users a lot of stress and time.

    Hi @tneville,

    So I had a spare minute….

    These work:
    g5LzQPx%2L3CkV3tc
    g5LzQPx2L3CkV3tc%
    %g5LzQPx2L3CkV3tc
    g5LzQPx}2L3CkV3tc
    }g5LzQPx2L3CkV3tc
    g5LzQPx2L3CkV3tc}
    g5LzQPx{2L3CkV3tc
    {g5LzQPx2L3CkV3tc
    g5LzQPx2L3CkV3tc{
    g5LzQPx>2L3CkV3tc
    g5LzQPx2L3CkV3tc>
    >g5LzQPx2L3CkV3tc
    g5LzQPx!2L3CkV3tc
    !g5LzQPx2L3CkV3tc
    g5LzQPx2L3CkV3tc!
    g5LzQPx[2L3CkV3tc
    [g5LzQPx2L3CkV3tc
    g5LzQPx2L3CkV3tc[
    g5LzQPx]2L3CkV3tc
    ]g5LzQPx2L3CkV3tc
    g5LzQPx2L3CkV3tc]
    g5LzQPx;2L3CkV3tc
    ;g5LzQPx2L3CkV3tc
    g5LzQPx2L3CkV3tc;
    g5LzQPx&2L3CkV3tc
    &g5LzQPx2L3CkV3tc
    g5LzQPx2L3CkV3tc&
    g5LzQPx@2L3CkV3tc
    @g5LzQPx2L3CkV3tc
    g5LzQPx2L3CkV3tc@
    g5LzQPx”2L3CkV3tc
    “g5LzQPx2L3CkV3tc
    g5LzQPx2L3CkV3tc”
    g5LzQPx’2L3CkV3tc
    ‘g5LzQPx2L3CkV3tc
    g5LzQPx2L3CkV3tc’

    These don’t work:
    g5LzQPx<2L3CkV3tc
    g5LzQPx2L3CkV3tc<
    <g5LzQPx2L3CkV3tc

    Hope that helps.

    Hi @redbullpeter,

    Incredible work! I will tag Yehuda on this and hopefully this is helpful to him as he is the developer for Post SMTP. ??
