I received the message off list. There is nothing wrong with the message 
per se. The message has several image/jpeg parts. Some of these parts 
have RFC 2047 encoded name= and filename= parameters. The first such 
part has headers

Content-Type: image/jpeg; 
name="=?UTF-8?Q?KF94_INFANTILES_=2D_NI=C3=91A=2Ejpg?="
Content-Disposition: inline; 
filename="=?UTF-8?Q?KF94_INFANTILES_=2D_NI=C3=91A=2Ejpg?="

which decode to

Content-Type: image/jpeg; name=" KF94 INFANTILES - NIÑA.jpg "
Content-Disposition: inline; filename=" KF94 INFANTILES - NIÑA.jpg "

These are valid headers, but are apparently responsible for the

There are other parts with RFC 2047 encoded headers:

Content-Type: image/jpeg; name="=?UTF-8?Q?KF94_INFANTILES_NI=C3=91O=2Ejpg?="
Content-Disposition: inline; 
filename="=?UTF-8?Q?KF94_INFANTILES_NI=C3=91O=2Ejpg?="

Content-Type: image/jpeg; 
name="=?UTF-8?Q?MASCARILLAS_INFANTILES_NI=C3=91A_KN95?=
	=?UTF-8?Q?=2Ejpg?="
Content-Disposition: inline;
	filename="=?UTF-8?Q?MASCARILLAS_INFANTILES_NI=C3=91A_KN95=2Ejpg?="

Content-Type: image/jpeg; 
name="=?UTF-8?Q?MASCARILLAS_INFANTILES_NI=C3=91O_KN95?=
	=?UTF-8?Q?=2Ejpg?="
Content-Disposition: inline;
	filename="=?UTF-8?Q?MASCARILLAS_INFANTILES_NI=C3=91O_KN95=2Ejpg?="

Content-Type: image/jpeg;
	name="=?UTF-8?Q?MASCARILLAS_INFANTILES_QUIRURGICAS_NI=C3=91A=2Ejpg?="
Content-Disposition: inline;
	filename="=?UTF-8?Q?MASCARILLAS_INFANTILES_QUIRURGICAS_NI=C3=91A=2Ejpg?="

Content-Type: image/jpeg;
	name="=?UTF-8?Q?MASCARILLAS_INFANTILES_QUIRURGICAS_NI=C3=91O=2Ejpg?="
Content-Disposition: inline;
	filename="=?UTF-8?Q?MASCARILLAS_INFANTILES_QUIRURGICAS_NI=C3=91O=2Ejpg?="

which decode to:

Content-Type: image/jpeg; name=" KF94 INFANTILES NIÑO.jpg "
Content-Disposition: inline; filename=" KF94 INFANTILES NIÑO.jpg "

Content-Type: image/jpeg; name=" MASCARILLAS INFANTILES NIÑA KN95.jpg "
Content-Disposition: inline;  filename=" MASCARILLAS INFANTILES NIÑA 
KN95.jpg "

Content-Type: image/jpeg; name=" MASCARILLAS INFANTILES NIÑO KN95.jpg "
Content-Disposition: inline;  filename=" MASCARILLAS INFANTILES NIÑO 
KN95.jpg "

Content-Type: image/jpeg;  name=" MASCARILLAS INFANTILES QUIRURGICAS 
NIÑA.jpg "
Content-Disposition: inline;  filename=" MASCARILLAS INFANTILES 
QUIRURGICAS NIÑA.jpg "

Content-Type: image/jpeg;  name=" MASCARILLAS INFANTILES QUIRURGICAS 
NIÑO.jpg "
Content-Disposition: inline;  filename=" MASCARILLAS INFANTILES 
QUIRURGICAS NIÑO.jpg "

And are responsible for the rest of the above messages.

This would seem to be a bug in the perl Mail::Pyzor::Digest module.
