I am getting this error when trying to send a post build email.
protocolConnect returning false, host=smtp.gmail.com, user=ALMPAV15$, password=
Where is it pulling this username and password from?
My configuration is set up correctly in the Email plug-in and when I send a test email from there it works.
This is full debug information:
Hello @msharoff and welcome to this community 
Are you using the mailer plugin or the email extension plugin?
I guess if you haven’t configured anything regarding the user sending the mail, the user could maybe be extracted from System Admin e-mail address configured in Jenkins?
Email extension plugin
Strange. What is your System Admin e-mail address configured in Jenkins?
I have my email address there. This section, correct?
The username it is using is the name of my server that Jenkins is running on.
It’s the same bug for me!
Is there a solution?
Randomly I found out, that the list of systems credentials for smtp authentication (a drop down list) is handled in a reverse way. If I want the first entry of the list I have to pick the last entry. Very strange.
If i choose system scope credential, email-ext show me password=<null> but if i change to global scope credential then password=<non-null>
My credentials are reported as not being used, even though I have very explicitly specified it. I have tried credentials with every possible scope and domain.
This is failing for both the standard email plugin and the extended email plugin.
It all worked smoothly 4 years or so ago when Jenkins was first set up. then it was disabled for several years and so I am having to set it all up again, and of course it is a newer and broken version now.
Any solutions found this issue?
Please post the solution if anyone got. Thanks in advance.
