Hi,
(Postman SMTP 2.0.22)
Post SMTP was working fine, with Office365API. But, it’s no longer working (on 3 different sites, which were all working).
Firstly, the POST SMPT test mail works!
Then, even for other emails, the log reports: “All good, mail sent”But the email never appears in the 365 account ‘Sent’ folder as it should and did. I’ve tried resetting the config and setting up Post SMTP again, but no change. I’m not quite sure how to debug further… can you help?
Incidentally, if I try the ‘Resend’ option from the Log I do get an error (that I don’t get for the test email) which is:
Client error:POST https://graph.microsoft.com/v1.0/me/sendMailresulted in a400 Bad Requestresponse: {“error”:{“code”:”InvalidInternetMessageHeader”,”message”:”The internet message header name ‘[“From’ should start with (truncated…)”Thank you!
-MarkHi folks, any suggestions to see what’s going on here? I was working perfectly, but after an update no longer does…
Many thanks
-MarkHi Mark,
That’s odd, have you checked the API permissions are correctly set for your Azure app?
Kind Regards,
TimHi Tim,
the API Permissions in Azure are User.Read, Delegated. The SMTP test email sends perfectly, and other emails appear in the log as Sent – but they never actually get sent. I’ve just looked at the ‘Session Transcript’ in the Log, and the test emails have a very full transcript, from the ‘contact’ form it just reads:
smtp:none:none://localhost:25
It suggests there’s something odd about the contact form, but its test email works fine too (with a full ‘Session Transcript’). Does that Session Transcript tell you anything?
(it’s more bizarre as this was all working fine when I first configured it)
Many thanks,
MarkHi Mark,
Ah, yes, the Session Transcript does help! Unfortunately this is a known bug. The developer is working on this, but is very busy so as of right now, I can’t give you a timescale for the fix.
Unfortunately your best bet is to look at Authenticated SMTP as a replacement.
Kind Regards,
Tim
