If you're trying to send feedback on Abena Products....
If you're trying to send feedback to Gary with XP Medical and ABAIP, DON'T send it to the firstname.lastname@example.org address. This address is kicking emails back and it looks like a DNS lookup problem or something.
Instead, if you want to send feedback, do it to email@example.com and he'll get it. I just tried it myself and it works just fine.
Hope this helps! Definitely send him your feedback since he's with Abena this week!
