Aggiungere per tutti i client mail di una rete la firma automatica (Es. informativa privacy) diventa piuttosto lavorioso e noioso. A questo problema ci viene incontro Altermime<\/a>\u00a0che integrato con postfix ci permette di raggiungere il nostro scopo. Ecco alcune indicazioni su come procedere :
\n
\n
\n[ad#ads]
\n
\n1. Installing alterMIME<\/p>\n

# wget http:\/\/www.pldaniels.com\/altermime\/altermime-0.2.2.tar.gz
\n# tar -xzvf altermime-0.2.2.tar.gz
\n# cd altermime-0.2.2
\n# make<\/p><\/blockquote>\n

# cp altermime \/usr\/bin\/
\n# chown root.root \/usr\/bin\/altermime
\n# chmod 755 \/usr\/bin\/altermime<\/p><\/blockquote>\n

2. Aggiunta utente con privilegi “user” per Altermime<\/p>\n

# useradd -r -c \u201cPostfix Filters\u201d -d \/var\/spool\/filter filter
\n# mkdir \/var\/spool\/filter
\n# chown filter.filter \/var\/spool\/filter
\n# chmod 750 \/var\/spool\/filter
\n\u00a0<\/p><\/blockquote>\n

3. Creare lo script\u00a0per\u00a0attivare\u00a0alterMIME<\/p>\n

#!\/bin\/sh
\nINSPECT_DIR=\/var\/spool\/filter
\nSENDMAIL=\/usr\/sbin\/sendmail
\n# Exit codes from
\nEX_TEMPFAIL=75
\nEX_UNAVAILABLE=69
\n# Clean up when done or when aborting.
\ntrap “rm -f in.$$” 0 1 2 3 15
\n# Start processing.
\ncd $INSPECT_DIR || { echo $INSPECT_DIR does not exist; exit $EX_TEMPFAIL; }
\n\/bin\/cat > in.$$ || { echo Cannot save mail to file; exit $EX_TEMPFAIL; }
\n\/usr\/local\/bin\/altermime –input=in.$$ –verbose –force-for-bad-html –log-syslog –disclaimer=\/etc\/postfix\/sign.text –disclaimer-html=\/etc\/postfix\/sign.text –xheader=”X-Copyrighted-Material: Please visit http:\/\/www.miosito.it” || { echo Message content rejected; exit $EX_UNAVAILABLE; }
\n$SENDMAIL “$@” < in.$$
\nexit $?
\n\u00a0<\/p><\/blockquote>\n

4. Creare il Disclaimer Files<\/p>\n

# joe \/etc\/postfix\/sign.text
\nAll’interno ci aggiungiamo ad esempio la informativa sulla privacy.<\/p><\/blockquote>\n

5. ora configuriamo postfix nel seguente modo:<\/p>\n

#joe \/etc\/postfix\/master.cf
\nSubito dopo la prima riga “smtp inet….” aggiungiamo il dfilt come indicato di seguito:<\/p><\/blockquote>\n

dfilt unix – n n – – pipe\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0 flags=Rq user=filter argv=\/etc\/postfix\/disclaimer -f ${sender} ${recipient}<\/p><\/blockquote>\n

6. Restart Postfix<\/p>\n
