Postfix Kegagalan pencarian sementara

Saya mencoba mengatur postfix, tetapi saya mendapatkan kesalahan "Kegagalan pencarian sementara"

Saya harus menunjukkan bahwa saya belum mengatur catatan DNS (dzervas.gr belum menunjuk server baru saya) Juga saya di arch linux x86_64

EDIT: Saya membuat kosong / etc / alias dan kemudian newaliases masalah baru (di telnet):

rcpt to: [email protected]
550 5.1.1 <[email protected]>: Recipient address rejected: User unknown in local recipient table

tapi!:

rcpt to: root@localhost
250 2.1.5 Ok
data
354 End data with <CR><LF>.<CR><LF>
hhahahahha
.
250 2.0.0 Ok: queued as <some-code>

EDIT 2: diselesaikan Recipient address rejected: User unknown in local recipient tabledengan menetapkan local_recipient_maps =di main.cf Namun, sekarang email saya ke [email protected] bisa antri! itu tidak masuk di /var/mail/vmail/dzervas.gr/dzervas/ sebagaimana mestinya!

Lari newaliases. Jika / etc / aliases tidak ada maka buat dulu, lalu jalankan newaliases.
Juga mungkin perbarui / tambahkan alias_maps = hash:/etc/aliaseske /etc/postfix/main.cf untuk menghilangkan peringatan lainnya.
Lalu coba lagi.
(Jika Anda menguji dengan telnet, Anda tidak perlu menggunakan DNS).

Masalah kedua: Hapus pertama $myhostname, $mydomain,dari mydestination, karena domain virtual seharusnya tidak terdaftar di sini.
Kemudian tambahkan (ke main.cf):

virtual_mailbox_domains=dzervas.gr

Muat ulang postfix dan coba lagi.

mynetworks membutuhkan rentang jaringan yang ketat

Dalam kasus saya, ada rentang ip yang salah di /etc/postfix/main.cf.

# Wrong; Temporary lookup failure
mynetworks = 172.16.0.0/8
# OK
mynetworks = 172.16.0.0/12

Ada kesalahan /var/log/maillogyang saya perhatikan kemudian.

4 Okt 13:47:54 postfix / smtpd [25056]: peringatan: bit alamat host bukan-nol dalam "172.16.0.0/8", mungkin Anda sebaiknya menggunakan "172.0.0.0/8" sebagai gantinya

Jika seseorang datang ke sini dari pencarian teratas di google dengan pencarian Temporary lookup failure, saya katakan silakan cek-cek $mynetworksformat Anda .

5 sen saya:

Saya memang mengubah main.conf, tetapi saya lupa memuat ulang postfix.

setelah memuatnya kembali berfungsi.
