[ingo] Generating Full From Header Sieve Script

I've been pulling my hair out trying to figure this out.  I want to 
generate a dovecot sieve filter based on the plain text From name.

For example, if I create a rule to match "From contains Doe" in ingo 
filter web page in horde I expect it to filter out any From header that 
contains a last name "Doe" in it.

This does not work, it only matches the email address, not the plain 
text name.  So a From header like "From: John Doe <john1966 at yahoo.com>" 
will filter on the search "John" but not "Doe" since "Doe" appears only 
in the plain text name and not the actual email address.

Ingo generates something like this

if address :all :comparator "i;ascii-casemap" :contains "From" "Doe"  {
     fileinto "JohnDoe";

If I create a filter from ISPConfig I get

if header :regex    ["from"] [".*Doe"] {
     fileinto "JohnDoe";

If I replace the "address :all" with "header" like this it works as 
expected from any address

if header :comparator "i;ascii-casemap" :contains "From" "Doe"  {
     fileinto "JohnDoe";

This question was asked over two years ago with no response, see 

Any ideas on how to either get this to work in this manner? It would 
make creating simple rules such as anything from say a family last name 
get filtered into one folder simply by searching the last name, versus 
applying many different email addresses to the filter.


Here's the other email from two years ago below
Hi list,

I have a small problem with the Ingo generated sieve script.
I am trying to filter by the plaintext name in the From header field (not
a mail address!).

Ingo generates the following if-condition:

if address :all :comparator "i;ascii-casemap" :contains "From" "Some
Name"  {

which does not match if I have incoming mail with a header line like this:

From: Some Name <email at address>

What works is the following sieve line:

if header :comparator "i;ascii-casemap" :contains "From" "Some Name"  {

However I can't get Ingo to generate something like this. Even if I use
the custom header field with "From" it is just transformed back into a
normal "From" rule.
