Hai, saya Arie, mau nanya2 soal pospik sama master2 disini.. :)
Saya ada 2 mail server, 1 untuk SMTP, 1 untuk MX yang ada pop3 nya.
Saya buat seperti ini karena spam yang banyak banget bikin mx saya
jadi berat, akhirnya beban ngirim email saya lempar ke smtp lain tapi
tetap 1 domain dan ada dalam 1 network.
Untuk smtp saya pakai postfix, untuk mx saya pakai qmail. Selama ini
pengiriman email selalu cepat dan tidak ada masalah, setelah saya coba
pakai SMTP-AUTH karena ada beberapa orang yang di luar kantor mau
kirim pake server kantor.
Ternyata sekarang (saya juga gak tau pasti sejak kapan dan kenapa),
email yang dikirim oleh beberapa user sering (gak selalu) keluar error
kalau saya cek di mail seperti ini.

btw, saya coba google, untuk permasalah 'timed out while receiving..'
saya sudah coba buat memasukan 0 di
/proc/sys/net/ipv4/tcp_window_scaling tapi tetap gak ada pengaruhnya.

Demikian, mohon masukan..
kirim ke yahoo ya? :)
yahoo sepertinya men terapkan system greylisting yg mem "babi buta"
(baru connect sudah di defer)
belum sempet smtp kita say helo langsung di defer hehehe(walaupun temporary)
tips, usahakan smtp kita mempunyai ptr record yg valid.
buat transport khusus seperti yg saya pernah baca di manual nya postfix..
"You're trying to send mail to difficult to reach sites (Hotmail, Yahoo,
etc.). Solution: set up transport map entries that give special
treatment (many parallel connections, short connection timeouts): "
/etc/postfix/main.cf:
transport_maps = hash:/etc/postfix/transport
deadbeats_destination_concurrency_limit = 50
/etc/postfix/transport:
hotmail.com deadbeats:
yahoo.com deadbeats:
/etc/postfix/master.cf:
deadbeats unix - - n - - smtp
-o smtp_connect_timeout=5 -o smtp_helo_timeout=5
