If your Lotus Notes server submits traffic from behind a static public IP address, we can associate requests from that IP address to one or more of your accounts depending on the email address sent from.
The service uses pattern matching to lookup the account, so a company with two accounts could set all emails from person1@company.com to be sent as SMS messages from one account and all other emails from another.
Please email support@esendex.net with your account reference only in the subject line to have this configured for your accounts.
