mailertls

Perl-based command line SMTP client with SSL/TLS support to test configurations of SMTP servers.

Special features like build-in Text-Substitution for subject and/or header-fields to test spam-filters. Include message texts from a string, file or dynamically created. Support HTML messages and attachments. Other options like number of repetitions and delay per TCP-connection to send multiple messages. Show complete client/server communication on STDOUT and optional log to external file(s) for debugging.

Usage

The easiest way to send a single mail is to use a configuration file. Except password and recipient, all parameters are used from this file. mailertls --config mailertls.conf --pass secret --to "username@example.com" The configuration can look like this:

  #file: mailertls.conf
  from="username@domain1.com"
  text="Hello, Message from mailtools"
  count=1

Text-substitution

This feature is useful if you want to send a huge amount of mails to one postbox. The substitutions are specified with curly braces around the filename(s). Each possible value is represented by one line.

  #file: mailertls.conf
  from="{fornames.txt}.{surnames.txt}@example.com"

Using a proxy

The following command sends a mail by using the given configuration file through a SOCKS4 proxy to hide the original source IP:

mailertls --config mailertlsconf --to "username@example.com" --proxy "1.2.3.4:1080:4"

Other examples

Sending with attachment

mailertls --config mailertlsconf --to "username@example.com" --attachment ~/filename

Multiple recipients

mailertls --config mailertlsconf --to "username@example.com" --to "user@example2.com"
