Mail considered spam by server

    Hello,

    I have had trouble since switching from Gmail through API to an SMTP server (with proper SPF/DKIM/DMARC settings). Using the PostSMTP mailer, I cannot send even a test e-mail. I get this: '' does not match the expected structure for a DNS hostname, '' does not appear to be a valid URI hostname, '' does not appear to be a valid local network name.

    Switching to PHPmailer works fine to send the e-mail. They’re considered spam by the relay. I’m not sure yet it’s due to how PostSMTP formats the messages, so I’ll hold off complaining for now ??

    Wordpress is hosted on a Google cloud VM, and hostname returns instance-1.

    Thanks,

    Clément

    I got confirmation from my e-mail provider that the server considers the e-mail spam because there is no MIME bodypart in the message. Is there an option somewhere to add this to the test e-mails?

    Hey @arsalantariq,

    I tried with the now-released 2.0.25 version, and no luck. Note that this is using PHPmailer, not the PostSMTP mailer.

    For PostSMTP mailer I get the error message in my initial post. I looked at the email log, and for the failing sessions all I see in the transcript is:

    This is the conversation between Postman and the mail server. It can be useful for diagnosing problems. DO NOT post it on-line, it may contain your account password.

smtps:login://mail.mailo.com:465

    When switching to PHPmailer, the transcript shows a complete connection session, as expected. So I think there’s another issue in the plugin…

    @cmoyroud thanks for updating us, let me look into it, will get back to you shortly.
