Can I connect to the IP address of your SMTP relay server?

We very strongly recommend you only connect to our service using the standard SMTP hostname:

mail.authsmtp.com

If your email application absolutely does not allow a server hostname and only allows an IP address to be specified please use:

62.13.128.189

IMPORTANT: Although it is unlikely we would need to change this IP address - it is possible - if you have any problems please contact us.
