Problem sending email via OVH Exchange after submitting a Notion/Tally form

How To
1

Hello,

I’m having a problem with my automation on Make. Here is the flow set up:

A Tally form is filled in and sends the data to Notion → :white_check_mark: Works correctly.

When data is sent from Notion to generate an e-mail via OVH Exchange (SMTP) → :cross_mark: Sending fails.

Problem details
Integration between Tally and Notion works well.

The problem occurs when Make tries to send an e-mail via OVH Hosted Exchange (SMTP).

I use the following settings for the SMTP connection:

SMTP server: ex5.mail.ovh.net

Port: 587

Security: TLS (with or without explicit TLS, tested both)

Username: contact@luminaverseagency.com

Password: (correct, tested on OVH Webmail)

Error encountered in Make: “AUTHENTICATE failed. Value must not be empty.”

What I tested
:check_mark: Correct connection to OVH Webmail with these credentials.
:check_mark: Tested SMTP sending with Thunderbird (works).
:check_mark: Checked OVH filters, no apparent blockage.
:check_mark: Change SMTP port to 465 with SSL (doesn’t work either).
:check_mark: Test sending to different e-mail addresses (no success).

My question
What exact settings should I use so that Make can send an e-mail via OVH Exchange after receiving the data from Notion?

Thanks for your help! :blush:
