-Options related to addressing:
- -f ADDRESS
- -t ADDRESS [ADDRESS ...]
- -cc ADDRESS [ADDRESS ...]
- -bcc ADDRESS [ADDRESS ...]
- -o reply-to=ADDRESS
-
--f ADDRESS
- This required option specifies who the email is from, I.E. the sender's
- email address.
-
--t ADDRESS [ADDRESS ...]
- This option specifies the primary recipient(s). At least one recipient
- address must be specified via the -t, -cc. or -bcc options.
-
--cc ADDRESS [ADDRESS ...]
- This option specifies the "carbon copy" recipient(s). At least one
- recipient address must be specified via the -t, -cc. or -bcc options.
-
--bcc ADDRESS [ADDRESS ...]
- This option specifies the "blind carbon copy" recipient(s). At least
- one recipient address must be specified via the -t, -cc. or -bcc options.
-
--o reply-to=ADDRESS
- This option specifies that an optional "Reply-To" address should be
- written in the email's headers.
-
-
-${colorGreen}Email Address Syntax${colorNormal}
-Email addresses may be specified in one of two ways:
- Full Name: "John Doe <john.doe\@gmail.com>"
- Just Address: "john.doe\@gmail.com"
-
-The "Full Name" method is useful if you want a name, rather than a plain
-email address, to be displayed in the recipient's From, To, or Cc fields
-when they view the message.
-
-
-${colorGreen}Multiple Recipients${colorNormal}
-The -t, -cc, and -bcc options each accept multiple addresses. They may be
-specified by separating them by either a white space, comma, or semi-colon
-separated list. You may also specify the -t, -cc, and -bcc options multiple
-times, each occurance will append the new recipients to the respective list.
-
-Examples:
-(I used "-t" in these examples, but it can be "-cc" or "-bcc" as well)
-
- * Space separated list:
- -t jane.doe\@yahoo.com "John Doe <john.doe\@gmail.com>"
-
- * Semi-colon separated list:
- -t "jane.doe\@yahoo.com; John Doe <john.doe\@gmail.com>"
-
- * Comma separated list:
- -t "jane.doe\@yahoo.com, John Doe <john.doe\@gmail.com>"
-

-${colorGreen}Message Options${colorNormal}
-Options related to the email message body:
- -u SUBJECT
- -m MESSAGE
- -o message-file=FILE
- -o message-header=EMAIL HEADER
- -o message-charset=CHARSET
- -o message-format=raw
-
--u SUBJECT
- This option allows you to specify the subject for your email message.
- It is not required (anymore) that the subject be quoted, although it
- is recommended. The subject will be read until an argument starting
- with a hyphen (-) is found.
- Examples:
- -u "Contact information while on vacation"
- -u New Microsoft vulnerability discovered
-
--m MESSAGE
- This option is one of three methods that allow you to specify the message
- body for your email. The message may be specified on the command line
- with this -m option, read from a file with the -o message-file=FILE
- option, or read from STDIN if neither of these options are present.
-
- It is not required (anymore) that the message be quoted, although it is
- recommended. The message will be read until an argument starting with a
- hyphen (-) is found.
- Examples:
- -m "See you in South Beach, Hawaii. -Todd"
- -m Please ensure that you upgrade your systems right away
-
- Multi-line message bodies may be specified with the -m option by putting
- a "\\n" into the message. Example:
- -m "This is line 1.\\nAnd this is line 2."
-
- HTML messages are supported, simply begin your message with "<html>" and
- sendEmail will properly label the mime header so MUAs properly render
- the message. It is currently not possible without "-o message-format=raw"
- to send a message with both text and html parts with sendEmail.
-
--o message-file=FILE
- This option is one of three methods that allow you to specify the message
- body for your email. To use this option simply specify a text file
- containing the body of your email message. Examples:
- -o message-file=/root/message.txt
- -o message-file="C:\\Program Files\\output.txt"
-
--o message-header=EMAIL HEADER
- This option allows you to specify additional email headers to be included.
- To add more than one message header simply use this option on the command
- line more than once. If you specify a message header that sendEmail would
- normally generate the one you specified will be used in it's place.
- Do not use this unless you know what you are doing!
- Example:
- To scare a Microsoft Outlook user you may want to try this:
- -o message-header="X-Message-Flag: Message contains illegal content"
- Example:
- To request a read-receipt try this:
- -o message-header="Disposition-Notification-To: <user\@domain.com>"
- Example:
- To set the message priority try this:
- -o message-header="X-Priority: 1"
- Priority reference: 1=highest, 2=high, 3=normal, 4=low, 5=lowest
-
--o message-charset=CHARSET
- This option allows you to specify the character-set for the message body.
- The default is iso-8859-1.
-
--o message-format=raw
- This option instructs sendEmail to assume the message (specified with -m,
- read from STDIN, or read from the file specified in -o message-file=FILE)
- is already a *complete* email message. SendEmail will not generate any
- headers and will transmit the message as-is to the remote SMTP server.
- Due to the nature of this option the following command line options will
- be ignored when this one is used:
- -u SUBJECT
- -o message-header=EMAIL HEADER
- -o message-charset=CHARSET
- -a ATTACHMENT
-
-
-${colorGreen}The Message Body${colorNormal}
-The email message body may be specified in one of three ways:
- 1) Via the -m MESSAGE command line option.
- Example:
- -m "This is the message body"
-
- 2) By putting the message body in a file and using the -o message-file=FILE
- command line option.
- Example:
- -o message-file=/root/message.txt
-
- 3) By piping the message body to sendEmail when nither of the above command
- line options were specified.
- Example:
- grep "ERROR" /var/log/messages | sendEmail -t you\@domain.com ...
-
-If the message body begins with "<html>" then the message will be treated as
-an HTML message and the MIME headers will be written so that a HTML capable
-email client will display the message in it's HTML form.
-Any of the above methods may be used with the -o message-format=raw option
-to deliver an already complete email message.

- -xu USERNAME
- -xp PASSWORD
- -o username=USERNAME
- -o password=PASSWORD
- -o tls=<auto|yes|no>
- -o timeout=SECONDS
-
--a ATTACHMENT [ATTACHMENT ...]
- This option allows you to attach any number of files to your email message.
- To specify more than one attachment, simply separate each filename with a
- space. Example: -a file1.txt file2.txt file3.txt
-
--xu USERNAME
- Alias for -o username=USERNAME
-
--xp PASSWORD
- Alias for -o password=PASSWORD
-
--o username=USERNAME (synonym for -xu)
- These options allow specification of a username to be used with SMTP
- servers that require authentication. If a username is specified but a
- password is not, you will be prompted to enter one at runtime.
-
--o password=PASSWORD (synonym for -xp)
- These options allow specification of a password to be used with SMTP
- servers that require authentication. If a username is specified but a
- password is not, you will be prompted to enter one at runtime.
-
--o tls=<auto|yes|no>
- This option allows you to specify if TLS (SSL for SMTP) should be enabled
- or disabled. The default, auto, will use TLS automatically if your perl
- installation has the IO::Socket::SSL and Net::SSLeay modules available,
- and if the remote SMTP server supports TLS. To require TLS for message
- delivery set this to yes. To disable TLS support set this to no. A debug
- level of one or higher will reveal details about the status of TLS.
-
--o timeout=SECONDS
- This option sets the timeout value in seconds used for all network reads,
- writes, and a few other things.

- specified sendEmail will try to connect to localhost:25 to deliver
- the message. THIS IS MOST LIKELY NOT WHAT YOU WANT, AND WILL LIKELY
- FAIL unless you have a email server (commonly known as an MTA) running
- on your computer!
- Typically you will need to specify your company or ISP's email server.
- For example, if you use CableOne you will need to specify:
- -s mail.cableone.net
- If you have your own email server running on port 300 you would
- probably use an option like this:
- -s myserver.mydomain.com:300
-
--o tls=<auto|yes|no>
- This option allows you to specify if TLS (SSL for SMTP) should be enabled
- or disabled. The default, auto, will use TLS automatically if your perl
- installation has the IO::Socket::SSL and Net::SSLeay modules available,
- and if the remote SMTP server supports TLS. To require TLS for message
- delivery set this to yes. To disable TLS support set this to no. A debug
- level of one or higher will reveal details about the status of TLS.
-
--o timeout=SECONDS
- This option sets the timeout value in seconds used for all network reads,
- writes, and a few other things.

-Options related to output:
- -l LOGFILE
- -v
- -q
-
--l LOGFILE
- This option allows you to specify a log file to append to. Every message
- that is displayed to STDOUT is also written to the log file. This may be
- used in conjunction with -q and -v.
-
--q
- This option tells sendEmail to disable printing to STDOUT. In other
- words nothing will be printed to the console. This does not affect the
- behavior of the -l or -v options.
-
--v
- This option allows you to increase the debug level of sendEmail. You may
- either use this option more than once, or specify more than one v at a
- time to obtain a debug level higher than one. Examples:
- Specifies a debug level of 1: -v
- Specifies a debug level of 2: -vv
- Specifies a debug level of 2: -v -v
- A debug level of one is recommended when doing any sort of debugging.
- At that level you will see the entire SMTP transaction (except the
- body of the email message), and hints will be displayed for most
- warnings and errors. The highest debug level is three.
