Hello everyone,

Question:
In the Mail Alias setting you can make an email alias and add an automatic reply.

Something line this:

> -----Original Message-----
> From: $FROM
> Sent:$DATE
> To: contact@mywebsite.com
> Subject: $SUBJECT
> Message: $BODY
-----

But the one receiving this gets it like this:

> -----Original Message----- > From: > Sent:Sat, 21 Jun 2025 16:12:21 +0200 > To: contact@mywebsite.com > Subject: this is the subject >Message: This is a multipart message in MIME format. ------=_NextPart_000_0117_01DBE2C7.4467E370 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit This is the body ------=_NextPart_000_0117_01DBE2C7.4467E370 Content-Type: text/html; charset="us-ascii" Content-Transfer-Encoding: quoted-printable 
 <= /p>
This is the = body

What makes this so weird?

If I don’t use the $BODY:

> -----Original Message-----
> From: $FROM
> Sent:$DATE
> To: contact@mywebsite.com
> Subject: $SUBJECT
-----

it looks like this:

> -----Original Message-----
> From: <ed@email.nl>
> Sent:Sat, 21 Jun 2025 16:16:09 +0200
> To: contact@mywebsite.com
> Subject: this is the subject
-----

I know, not using the $BODY solve some of this issue.
But I want to know why??

Any idea’s ??

Please and Thank you. :wink:
