SRMP Client V.1.0.0

#SRMP(Send/Receive Mail Protocol) è un "Protocollo" creato da me(MRtecno98)
#per inviare "email" da un dispositivo all'altro
#Per settare il programma prima di tutto dovete avere una struttura di cartelle creata dallo script di setup server
#Poi inserite in SERVER l'url del server in cui si trova l'albero di cartelle, in SERVER_USR l'usr dell'ftp del server
#e in SERVER_PSW la password dell'ftp
#Poi inserite in SERVER_DIR il nome della cartella dei dati del server, se non avete cambiato alcuna impostazione nel setup
#si chiamerà SRMP
