    I got an issue when I connect the Easy WP SMTP plugin without permission of “Insecure SSL Certificates”. The Mailserver certificate is secure and valid, it is an wildcard ssl certificat. If I set “Allow Insecure SSL Certificates” it works fine. Any ideas why it will not work with wildcard certificates?

    Any help is appreciated .

    Hi, can you enable debug mode and then carry out a test. Report back with any findings.

    Thank you

    This is the result out of the debug logfile:
    —————————————————————-
    Easy WP SMTP debug log file
    Cryptor::decryptString() – data length 12 is less than iv length 16Cryptor::decryptString() – data length 12 is less than iv length 16Cryptor::decryptString() – data length 12 is less than iv length 16

    This is the debug log form on the testmail site:
    —————————————————————-
    CLIENT -> SERVER: EHLO euronethosting.shop
    CLIENT -> SERVER: STARTTLS
    CLIENT -> SERVER: EHLO euronethosting.shop

    SMTP Error: Could not authenticate.CLIENT -> SERVER: QUIT

    One issue or something unexpectable: the correct mail server is mail.euronetmail.com and this one is correct entered in the first page.

    Hi,

    SMTP ERROR: Password command failed: 535 5.7.8 Error: authentication failed: UGFzc3dvcmQ6

    Can you verify with your host the above error message?

    Thank you

    when I now check, debug log remains empty…..

    the debug log at the test sending page,

    when

    <<Allows insecure and self-signed SSL certificates on SMTP server. It’s highly recommended to keep this option disabled>>

    is enabled:

    CLIENT -> SERVER: EHLO euronethosting.shop
    CLIENT -> SERVER: STARTTLS
    CLIENT -> SERVER: EHLO euronethosting.shop
    CLIENT -> SERVER: AUTH LOGIN
    CLIENT -> SERVER: YmVzdGVsbHVuZ0BldXJvbmV0aG9zdGluZy5zaG9w

    CLIENT -> SERVER:

    CLIENT -> SERVER:
    CLIENT -> SERVER: .
    CLIENT -> SERVER: QUIT

    So you can see it works fine.

    In case of disabling this debug log on test page remains empty but with a failure message (Following error occurred when attempting to send test email:
    SMTP Error: Could not connect to SMTP host.) and a red strip at the left side.

    Hi,

    Your best option is to speak to your host about this issue. I am curious to know myself why it is not working with your host.

    Thank you

    I think the issue is coming out of the plugin, any client can connect to the host (mail.euronetmail.com) outlook, thunderbird, etc. just your plugin. If I connect to a mailhost with a non wildcard certificate, it works fine. Just with the wildcard it will only work with the enabled function:
    <<Allows insecure and self-signed SSL certificates on SMTP server. It’s highly recommended to keep this option disabled>>

    Best regards Christoph

    Hi,

    checked the ssl certs and replaced them, now it works fine.

    Thank you for your assistance.
