BMS My Company | Outbound Email | Testing custom SMTP connections


BMS uses Kaseya's internal outbound mail server to send out emails to clients. For this process, BMS uses SendGrid as Kaseya's outgoing mail server. You can find the outbound mail settings at Admin > My Company > Outbound Email. An MSP can use either BMS' default outbound mail server or a custom mail server of their choice. By default, the Use Custom SMTP Settings option is set to No. This article describes the steps to test a custom SMTP connecting using a specific tool called SMTPer.

How SendGrid Works

SendGrid is a cloud-based SMTP provider that allows you to send email without having to maintain email servers. With SendGrid, Kaseya's outbound emails are managed at all different platforms including BMS and Vorex.

BMS' and Vorex's default outbound emails relay the emails from the application to the client through SendGrid. When an email is sent out of BMS it reaches Kaseya's SendGrid with the sender address provided in the BMS email template. It is then relayed to the intended address. Our outbound SMTP email relay:
