testmsg 0.0.8

Simple CLI tool to generate/send valid RFC822 email messages (with DKIM optionally)

testmsg

Generate RFC822 compliant e-mail messages for tests and send it over SMTP.

While it's easy to send test messages like echo asdf | mail [e-mail] or via telnet mx.example.com 25 I need a tool which:

• Generates valid messages
• Messages does not looks spammy or very suspicious
• Easy to use and repeat test
• Ability to customize messages
• Work well with msmtp or other full-featured SMTP client (e.g. which can send over secure SMTP connection with authentication)

Installation

pip3 install testmsg

$ testmsg --to [e-mail]  --lorem

Content-Transfer-Encoding: quoted-printable
MIME-Version: 1.0
Subject: Sent with github.com/yaroslaff/testmsg

Options

Sending message

To actually send message via SMTP server add --send localhost or (if you need really powerful SMTP client features) pipe to msmtp:

testmsg --lorem --to [e-mail] --from [e-mail] | msmtp --host mail.example.net -v --tls=on --tls-starttls=on --auth=on --user=[e-mail] --passwordeval "echo YourPass" -f [e-mail] [e-mail]

Customize message

Use --from, --to and --subject to override basic properties of message, use --add HEADER VALUE to add custom header(s).

Default message text is empty, use --text "blah blah blah" or --lorem or --msg PATH or --msg - .(to read from stdin). Add --time to add current time as an prefix to text.

Add attachments

Use --attachment (or --att) to add attachments: --att FILE1 FILE2 ...
