special character less than not allowed and fails authentication if used

@digitaliway

Hi,

Hope you are doing good.

Less than sign in your email or password? can you share an example email address?

Thanks

password only/ if I have a password like this: 1aD@#<98+=] it will fail authentication.

below pass Does not work:
1aD@#<98+=]

below pass does work:
1aD@#>98+=]

thank you for the reply.

Thanks, let me know which mailing service you are using.

Also share Post SMTP Diagnostic test report.

Thanks

I am using SMTP on port 587 STARTTLS CRAM-MD5. This fails on multiple websites that I tested so it is not just the one website I am working with.

@digitaliway ok but let me know which mailing service you are using in POST SMTP. like Gmail, Office 365, or Server domain mail?

We are using server domain mail. The mail server software is SmarterMail. I can confirm that the passwords work in mail clients and in the webmail interface but fails with the plugin. If you provide me a direct email for you I will send a diagnostic report but I do not want to expose my host info in the forum.

@digitaliway It’s not allowed on this forum to provide email, Diangsotic reports have just PHP version and plugin names there is not confidential info you can provide here.

Thanks
