I get this happening all the time with MailMate, but, it's not related 
to Exchange invitations.  Indeed, I've no idea what is causing it, but 
the relevant headers are:

 From: mail-list at domain.com (user at company.com)
To: "mailinglist at domain.com" <mailinglist at domain.com>
X-Mailer: Apple Mail (2.2104)
X-MS-Exchange-Messagesentrepresentingtype: 1
X-MS-Exchange-Transport-Fromentityheader: Hosted
Sender: mail-list at domain.com
Errors-To: mail-list at domain.com
List-Post: <mailto:mailinglist at domain.com>
Comments: Did not say From: user at company.com at sender's request


Obviously, I've modified from the original, but, the result is the same 
- MailMate displays the "From" as "mail-list at domain.com" rather than the 
actual user who sent the message.  In my case, Sender is also not the 
actual user's address.

Curiously, FastMail sees user at company.com for the sending address, as 
does Mail.app - it's only MailMate which seems to get slightly confused.

If I try to reply to these messages, the reply doesn't go to the user in 
MailMate, but does in FastMail/Mail.app/etc.

Any way to get the user at company.com to be recognised here?
