+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>"

+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.

+ -o username=USERNAME

+ -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,

+ connect to to deliver your email message to. If this option is not
+ 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:

+ -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.
