As of this writing, the Mexican Immigration Department says that:
No requerirá visa mexicana el extranjero que presente alguno de los siguientes documentos:
a) Documento que acredite residencia permanente en Canadá, Estados Unidos de América, Japón, el Reino Unido de la Gran Bretaña e Irlanda del Norte, cualquiera de los países que integran el Espacio Schengen, así como en los países miembros de la Alianza del Pacífico (Chile, Colombia y Perú).
b) Visa válida y vigente de Canadá, de los Estados Unidos de América, Japón, el Reino Unido de la Gran Bretaña e Irlanda del Norte o cualquiera de los países que integran el Espacio Schengen.
or, in English (my unofficial translation):
A foreigner who presents one of the following documents does not require a Mexican visa:
a) A document that proves permanent residence in Canada, the United States of America, Japan, the United Kingdom of Great Britain and Northern Ireland, any of the countries that make up the Schengen Area, or the Pacific Alliance (Chile, Colombia, and Peru).
b) A valid, in-force visa from Canada, the United States of America, Japan, the United Kingdom of Great Britain and Northern Ireland, or any of the countries that make up the Schengen Area.
Depending on the type of permesso di soggiorno that you have, it may be a permanent residence card (document type "a" above) or a temporary residence card. If it is a temporary residence card, you can not use it to enter Mexico, but in that case you probably also have a valid visa (document type "b" above) for entering Italy, a country in the Schengen Area. Moldovan citizens normally must obtain a visa to visit Mexico, but assuming you have one of these documents, you can use that document to enter Mexico without obtaining a separate Mexican visa.
