swaks ist das Swiss Army Knife für SMTP.
swaks› primary design goal is to be a flexible, scriptable, transaction-oriented SMTP test tool. It handles SMTP features and extensions such as TLS, authentication, and pipelining; multiple version of the SMTP protocol including SMTP, ESMTP, and LMTP …
Wenn man den Mail Versand per SMTP schnell testen möchte ohne sich dabei mit der Konfiguration eines Mail Clients rumzuplagen, geht das am schnellsten auf der Konsole. Wenn man nicht mit Linux arbeitet, kann man unter OS X swaks mit MacPorts rasch installieren:
sudo port install swaks
Und schon steht das swaks-Utility zum testen zur Verfügung:
swaks --to info@openstream.ch --server servername.openstream.ch --auth-user client.domain.ch
Daraufhin kommt eine Passwort-Eingabeaufforderung und bei Erfolg folgende Ausgabe:

Wenn der Status 250 zurück gemeldet wird, wurde die Testnachricht erfolgreich in die Mail Queue des SMTP-Servers eingereiht. Ein Blick in unser Postfach info@openstream.ch zeigt, dass die Testnachricht angekommen ist.
Der Mail Header der Test-Mail sieht wie folgt aus:
