Does mailbox.org strip certain headers?

Does mailbox.org strip certain headers from emails sent through the SMTP service? I have identical setups for my email client with mailbox.org and my work's email provider. In the case of mailbox, the "user-agent" field is not present in my emails on the receiving side, while in the case of my other provider it is. Is this field intentionally stripped out by mailbox.org?

It also appears that the first "received from" header might have been removed (the one of smtp.mailbox.org receiving my email).

It's not that I care so much about the user-agent field (and its removal could be happening elsewhere), but it would be nice to control which headers are removed by mailbox.org, if any.

Thank you for any clarification on the matter.
