2.3 Advanced MML Example

Here’s a complex multipart message. It’s a ‘multipart/mixed’ that contains many parts, one of which is a ‘multipart/alternative’.

<#multipart type=mixed>
<#part type=image/jpeg filename=~/rms.jpg disposition=inline>
<#multipart type=alternative>
This is a plain text part.
<#part type=text/enriched name=enriched.txt>
<center>This is a centered enriched part</center>
<#/multipart>
This is a new plain text part.
<#part disposition=attachment>
This plain text part is an attachment.
<#/multipart>

And this is the resulting MIME message:

Content-Type: multipart/mixed; boundary="=-=-="
