    Hi,
    Since the update to WP 5.5.1 I get this error trying to send a test from WP Mail SMTP

    It’s a multisite and the error is on multiple websites.

    I tried to remove the password constant from wp-config but the problem is still there.

    What could cause this?
    Thanks in advance,
    ARiane

    Hi,
    After the latest update test mails are sending again. However, the form won’t send, I get this message on WP mail SMTP page:
    EMAIL DELIVERY ERROR: the plugin WP Mail SMTP v2.4.0 logged this error during the last time it tried to send an email:

    Mailer: Other SMTP
    SMTP Error: data not accepted.

    What could cause this?

    Thanks in advance,
    Ariane

    HI @arianegordijn,

    The fatal error appears when you update WordPress to the latest version but still using the older version of the WP Mail SMTP plugin. I’m glad you sorted that out.

    Mailer: Other SMTP
    SMTP Error: data not accepted.

    The error message indicates that there’s an issue with email settings in the form. Please make sure the ‘From Email’ in the email settings matches the email you’ve authenticated in SMTP, and check other email notification settings.

    I hope this helps!
