Menambahkan Trusted Domain di Zimbra
ada kalanya domain domain.co.id atau gmail.com masuk junk atau dianggap spam.
nah untuk mengantisipasi agar tidak dianggap spam adalah memasukkan daftar domain ke dalam antispam rule didalam file /opt/zimbra/conf/salocal.cf.in. Jangan lupa backup terlebuh dahulu sebelum merubah file konfig, dan tambahkan white list berikut:
#trusted domain.co.id
def_whitelist_from_rcvd *@domain.co.id domain.co.id
def_whitelist_from_rcvd *@gmail.com gmail.com
config akhir salocal.cf.in
# This is the right place to customize your installation of SpamAssassin.
#
# See 'perldoc Mail::SpamAssassin::Conf' for details of what can be
# tweaked.

lalu restart :
# zmmtactl restart
# zmamavisdctl restart
jika sudah, saatnya sekarang mencoba apakah antispam nya sudah berjalan atau belum. maka kita harus mengirim dengan cara spamming`
caranya, telnet ke mail server lain:
[user@host ~]$ telnet localhost 25
lalu akan muncul reply:
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.

ketik quit untuk keluar dari telnet..
lalu cek inbox email corporate dan bisa kita lihat di header email bahwa email gmail.com tidak dianggap spam (lihat bagian cetak tebal) padahal kita sudah melakukan spamming (big grin)(smile)
