| -t 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: | |

| ${colorBold}MESSAGE DOCUMENTATION${colorNormal} | |
| ${colorGreen}Message Options${colorNormal} | |
| Options related to the email message body: | |
| -u SUBJECT | |
| -m MESSAGE | |
| -o message-file=FILE | |
| -o message-content-type=<auto|text|html> | |
| -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-content-type=<auto|text|html> | |
| This option allows you to specify the content-type of the email. If your | |
| email message is an html message but is being displayed as a text message | |
| just add "-o message-content-type=html" to the command line to force it | |
| to display as an html message. This actually just changes the Content-Type: | |
| header. Advanced users will be happy to know that if you specify anything | |
| other than the three options listed above it will use that as the vaule | |
| for the Content-Type header. | |
| -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. | |

| -a ATTACHMENT [ATTACHMENT ...] | |
| -xu USERNAME | |
| -xp PASSWORD | |
| -o username=USERNAME | |
| -o password=PASSWORD | |
| -o tls=<auto|yes|no> | |
| -o timeout=SECONDS | |
| -o fqdn=FQDN | |
| -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. | |
| -o fqdn=FQDN | |
| This option sets the Fully Qualified Domain Name used during the initial | |
| SMTP greeting. Normally this is automatically detected, but in case you | |
| need to manually set it for some reason or get a warning about detection | |
| failing, you can use this to override the default. | |

| ${colorBold}NETWORKING DOCUMENTATION${colorNormal} | |
| ${colorGreen}Networking Options${colorNormal} | |
| Options related to networking: | |
| -s SERVER[:PORT] | |
| -b BINDADDR[:PORT] | |
| -o tls=<auto|yes|no> | |
| -o timeout=SECONDS | |
| -s SERVER[:PORT] | |
| This option allows you to specify the SMTP server sendEmail should | |
| 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 | |
| If you're a GMail user try: | |
| -s smtp.gmail.com:587 -xu me\@gmail.com -xp PASSWD | |
| -b BINDADDR[:PORT] | |
| This option allows you to specify the local IP address (and optional | |
| tcp port number) for sendEmail to bind to when connecting to the remote | |
| SMTP server. This useful for people who need to send an email from a | |
| specific network interface or source address and are running sendEmail on | |
| a firewall or other host with several network interfaces. | |
| -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. | |

| ## OUTPUT | |
| ($topic eq 'output') && do { | |
| print <<EOM; | |
| ${colorBold}OUTPUT DOCUMENTATION${colorNormal} | |
| ${colorGreen}Output Options${colorNormal} | |
| 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. | |
