Which SMTP Server Should I Use for My Site?
Click here if you're looking for the SMTP settings for your email software
If you need to send emails from your site, you can use localhost or 127.0.0.1 on port 25 to send your emails, without authentication.
If you use PHP, you can also use the mail() function directly.
In both cases, make sure the sender address matches your domain name and actually exists (e.g. contact@mapetitentreprise.re and not noreply@mapetitentreprise.re). An invalid sender, or one not hosted on your server (e.g. mapetiteentreprisee@gmail.com), may be blocked by our anti-spam system or the recipient's.
