Is Axigen's Sendmail crippled in the free version?

Hello Support - I am running the free version of Axigen Mail-Server 10.3.3.2 (Linux/x64) in my home (SOHO). I have followed the instructions that I could find, to substitute Axigen’s version of Sendmail for the one that came with my Linux (OpenSuSE 15.3) system. I have gotten it to send an “email” manually but the body of the email message is not sent. Instead I receive a small ad -

Email sent using Axigen Free Mail Server:
Free Mail Server | Axigen

My question, shown in the subject line, is this the expected behavior or have I done something wrong in setting up Sendmail that is causing it to not send the body of my messages?

Thanks in advance for helping me with this issue. Marc

Well never-mind, not sure what I did, in all my efforts and fiddling around with settings in the WebAdmin app, but something got Sendmail to sit up and bark right! I am getting the message bodies sent now…
