Error [120] Ran into problems sending Mail. Response : 554.5.2.252

Hi! I’m trying to send an email to a third party on Dolibarr 14.0.4. The email sender for manual emails is set to “user email” and I would like to use my email address to send email instead of using the organization email address. But I failed and received the following message : “Error [120]: Ran into problems sending Mail. Response: 554 5.2.252 SendAsDenied; noreply@mycompany.com not allowed to send as user@mycompany.com STOREDRV.Submission.Exception:SendAsDeniedException.MapiExceptionSendAsDenied; Failed to process message due to a permanent exception with message Cannot submit message. 0.3525”
Thank you.

Hello,

You need to ask your email provider.

Thanks for your reply.
