Rekan2 Yth,
Mohon masukkannya untuk masalah yg sedang saya hadapi saat ini.
kami mempunyai webmail (squirrelmail 1.4.9a + postfix-2.3.4) yg
terkoneksi ke exchange server dimana user login ke webmail menggunakan
autentikasi active directory. baru2 ini webmail tsb dibanjiri oleh spam
dengan log spt dibawah ini :

dan seterusnya....hingga mencapai hampir 200an email. Saya masih belum
mengerti apakah ini masalah squirrelmail atau postfix.
pertanyaan saya, bagaimana caranya email dari i...@email.com (bukan dari
domain kami) bisa mengirimkan email dan autentikasi via squirrelmail?
postconf saya sbb:
alias_database = hash:/etc/postfix/aliases
alias_maps = hash:/etc/postfix/aliases
command_directory = /usr/sbin
config_directory = /etc/postfix
daemon_directory = /usr/libexec/postfix
debug_peer_level = 2
disable_vrfy_command = yes
inet_interfaces = all
mail_owner = postfix
mailq_path = /usr/bin/mailq
manpage_directory = /usr/local/man
mydestination = localhost
mydomain = domain kami
myhostname = webmail.domain kami
mynetworks = 127.0.0.0/8
newaliases_path = /usr/bin/newaliases
queue_directory = /var/spool/postfix
relay_domains = $mydomain
relayhost = [192.168.0.10]
sendmail_path = /usr/sbin/sendmail
setgid_group = postdrop
smtpd_recipient_restrictions =
permit_mynetworks,
check_relay_domains,
check_sender_access
hash:/etc/postfix/maps/check_sender_access,
permit
check_sender_access
domain kami OK
Mohon pencerahannya
terima kasih
Andri
