Yes, absolutely.
Honestly, I get a real headache when I read through all the posts here.
You need someone who has sufficient technical knowledge to check the current configuration, find out how many emails are actually being sent / day, what triggers those emails and if they are authorized / valid or not (which implies some kind of abuse).
Once this is done the setup most likely needs to be changed to use a proper SMTP provider (there are plenty like SES, etc.).
This isn't exactly rocket science, but certainly more difficult than launching a browser on a smartphone.
