    hi, suddenly since yesterday the emails in html format return this error: SMTP error: data not accepted

    The plugin is already set with “Force from email” and I also tried to disable it.
    If I test the emails working in clear text, those in html do not.
    But it’s a makeshift bug as it has been working since December.

    I send you the full error log (the xxx I added them to not expose sensitive emails here in the forum)

  • Hi @marketwo,

    Thanks for the details. The error indicates that the SMTP server isn’t accepting the data sent with the email. Please make sure the ‘From Email’ you’re using is hosted by the SMTP server you’re connecting to. It also looks like the email is rejected as spam because of it being the test email. You might need to contact your SMTP server support to investigate the issue or switch to other available mailers.

    I hope this helps!

    HI @marketwo – We haven’t heard from you in about a week, so I’m going to go ahead and mark this ticket resolved. If you still have questions, though, please feel welcome to continue the conversation.
