Saya memiliki server SMTP, untuk keperluan pertanyaan ini, sebut saja: smtp.mydomain.com.
Bagaimana saya memeriksa apakah server SMTP sedang bekerja? Bisakah saya mengirim email secara manual dari commandline Linux?

Jawaban:
Sintaks untuk membuat koneksi jaringan mentah menggunakan telnet adalah ini:
telnet {domain_name} {port_number}
Jadi telnet ke server smtp Anda suka
telnet smtp.mydomain.com 25
Dan salin dan tempel di bawah ini
helo client.mydomain.com
mail from:<sender@mydomain.com>
rcpt to:<to_email@mydomain.com>
data
From: test@mydomain.com
Subject: test mail from command line
this is test number 1
sent from linux box
.
quit
Catatan: Jangan lupa tanda "." di akhir yang mewakili akhir pesan. Garis keluar "keluar" mengakhiri sesi.
hello velanapps.com
Anda harus menulis helo velanapps.com
dan jika Anda ingin tahu ekstensi smtp mana yang tersedia, Anda harus menulis ehlo velanapps.com
, seperti pada Contoh SMTP
Satu-satunya hal tentang menggunakan telnet untuk menguji postfix, atau SMTP lainnya, adalah Anda harus mengetahui perintah dan sintaksisnya. Sebagai gantinya, cukup gunakan swap :)

Tidak yakin apakah ini membantu atau tidak, tetapi ini adalah alat baris perintah yang memungkinkan Anda mengirim surat uji dari server SMTP secara primitif. http://code.google.com/p/woodpecker-tester/
