SMTP service

Overview

The SMTP service is freely accessible in the service area and billed automatically according to the use that is made of it.

It allows you to send notifications from your applications hosted on Cloud Avenue, including to your technical services.

Features

• Emails are scanned and those containing viruses are rejected
• Emails are authenticated using several mechanisms
  • DKIM and DMARC for sender domain protection (cloudavenue.orange-business.com)
  • SPF for protection of public IPs of SMTP servers
• TLS is configured in opportunistic mode, encrypting communications between client and SMTP server if the client requests and supports it

Limits

• SMTP servers only accept messages from VMs hosted on Cloud Avenue
• The sender address must be smtp-service@cloudavenue.orange-business.com
• The maximum message size allowed is 15MB
• The maximum number of simultaneous connections per client is 10
• The maximum number of connections per minute of a client is 60
• The maximum number of emails sent per 24 hours is 2000

Billing

Accessible via the use of NAT, the service is billed by IP and according to the use automatically recorded by following tiers :

Exceeding a level during a single day of the month changes the month to the corresponding rate.

Note that several VMs can use the same IP and group their emails in the same count, sharing it. On the other hand, several braided IPs can be used to benefit from several counts.

Use the service

The use of the service requires the pre-configuration of NAT access to the service area.

The configuration of your software/client mail must then be carried out as follows :

• SMTP server IP address: 57.199.209.206
• Port : 25
• Sender address: smtp-service@cloudavenue.orange-business.com
• Recipient address: any valid email address that must receive the message
• The subject of the email must not be empty
• The body of the mail must not be empty
