Email (SMTP) delivery

AEVU sends invitations, password recovery messages, billing receipts and similar notices. Email goes through one platform sender.

Platform operator only

This is configured by the AEVU platform operator on the server, not by organisation or workspace admins. Admins can edit the wording of messages in Settings → Email templates (Email templates).

Settings the server needs

Set outside any committed file, as environment variables (double underscores) or user secrets:

Key	Meaning
Smtp:Host / PMO__Smtp__Host	Mail server host name
Smtp:Port	Port (587 by default)
Smtp:User	The mailbox sign-in name
Smtp:Password	Its password
Smtp:From	The public sender address, for example hello@aevupm.com
Smtp:FromName	Display name (default AEVU)

Email counts as configured only when Host, User, From and Password are all set.

Using Microsoft 365 as the sender

1. Use the mailbox's real sign-in name (for example name@tenant.onmicrosoft.com) as User. An alias is rejected with error 5.7.3. Put the public address in From.
2. In the Exchange admin center → Settings → Mail flow, make sure Turn off SMTP AUTH protocol for your organization is unticked.
3. In the Microsoft 365 admin center → Users → the mailbox → Mail → Manage email apps, turn on Authenticated SMTP.
4. Wait: changes can take 30 minutes or more. Security defaults or MFA enforcement on the mailbox can still block basic sign-in.

Basic-auth SMTP is being phased out by Microsoft

If Microsoft withdraws it for your tenant, a different route (sending through Microsoft Graph) will be needed.

Development

In development all mail is caught by a local mail catcher (Mailpit) instead of being sent; that is switched off in deployed environments.

Checking it works

Send a test invitation or password-recovery email to a mailbox you control. A real in-app send through Microsoft 365 has not yet been verified end to end; a direct SMTP send has.

Problems

Symptom	Likely cause
Nothing arrives	Email not fully configured, or the catcher is still on
5.7.3 rejected	User is an alias; use the sign-in name
Authentication fails	SMTP AUTH or Authenticated SMTP not enabled, or still propagating
Spam folder	Set up SPF/DKIM for the From domain with your mail provider
