Freron MailMate

Hi there,

The default reply string/format seems to be:

defaults write com.freron.MailMate MmReplyWroteString -string 'On %e %b %Y, at %k:%M, ${from.name:${from.address}} wrote:'

Would it be possible to customize this to use X-SimpleLogin-Envelope-From and X-SimpleLogin-Original-From , but only for e-mails originating from SimpleLogin?
I tried using them, but it's not working (i get an empty result.)

Here's some example info from an incoming e-mail:

X-SimpleLogin-Type: Forward
X-SimpleLogin-Envelope-From: support@xxxx.zendesk.com
X-SimpleLogin-Original-From: Maria
 <support@xxxx.zendesk.com>
X-SimpleLogin-Envelope-To: user@mail.mydomain.nl
From: "Erika"
 <support_at_xxxx_zendesk_com_ylsjheaqa@simplelogin.co>
Reply-To: 
 support_gexyzp417-37gcy_at_xxxx_zendesk_com_gekezgq417@simplelogin.co
To: "user@mail.mydomain.nl" <user@mail.mydomain.nl>

Thank you!
