I have a problem sending e-mail notifications from Veeam Backup & Replication. Our mail server is sending this kind of error:
- Code: Select all
Helo command rejected: need fully-qualified hostname (System.Net.Mail.SmtpException)
As you can see, our mail server requires FQDN hostname. In Windows I can only set simple hostname without dots (like "Veeam") and then add a domain name (like "company.com"). Entire PC name is correct ("Veeam.company.com") and would meet mail server requirements, but Veeam is only sending a simple Windows hostname "Veeam" in e-mail notification. I would like to request a feature to customize hostname sent by Veeam software and force sending FQDN hostname.
