|
|
|
1365 |
-t ADDRESS [ADDRESS ...]
|
|
|
1366 |
-cc ADDRESS [ADDRESS ...]
|
|
|
1367 |
-bcc ADDRESS [ADDRESS ...]
|
|
|

-o reply-to=ADDRESS
|
|
|
1369 |
|
|
|
1370 |
-f ADDRESS
|
|
|
1371 |
This required option specifies who the email is from, I.E. the sender's
|
|
|
1372 |
email address.
|
|
|
1373 |
|
|
|
1374 |
-t ADDRESS [ADDRESS ...]
|
|
|
1375 |
This option specifies the primary recipient(s). At least one recipient
|
|
|
1376 |
address must be specified via the -t, -cc. or -bcc options.
|
|
|
1377 |
|
|
|
1378 |
-cc ADDRESS [ADDRESS ...]
|
|
|
1379 |
This option specifies the "carbon copy" recipient(s). At least one
|
|
|
1380 |
recipient address must be specified via the -t, -cc. or -bcc options.
|
|
|
1381 |
|
|
|
1382 |
-bcc ADDRESS [ADDRESS ...]
|
|
|
1383 |
This option specifies the "blind carbon copy" recipient(s). At least
|
|
|
1384 |
one recipient address must be specified via the -t, -cc. or -bcc options.
|
|
|
1385 |
|
|
|
1386 |
-o reply-to=ADDRESS
|
|
|
1387 |
This option specifies that an optional "Reply-To" address should be
|
|
|
1388 |
written in the email's headers.
|
|
|
1389 |
|
|
|
1390 |
|
|
|
1391 |
${colorGreen}Email Address Syntax${colorNormal}
|
|
|
1392 |
Email addresses may be specified in one of two ways:
|
|
|
1393 |
Full Name: "John Doe <john.doe\@gmail.com>"
|
|
|
1394 |
Just Address: "john.doe\@gmail.com"
|
|
|
1395 |
|
|
|
1396 |
The "Full Name" method is useful if you want a name, rather than a plain
|
|
|
1397 |
email address, to be displayed in the recipient's From, To, or Cc fields
|
|
|
1398 |
when they view the message.
|
|
|
1399 |
|
|
|
1400 |
|
|
|
1401 |
${colorGreen}Multiple Recipients${colorNormal}
|
|
|
1402 |
The -t, -cc, and -bcc options each accept multiple addresses. They may be
|
|
|
1403 |
specified by separating them by either a white space, comma, or semi-colon
|
|
|
1404 |
separated list. You may also specify the -t, -cc, and -bcc options multiple
|
|
|
1405 |
times, each occurance will append the new recipients to the respective list.
|
|
|
1406 |
|
|
|
1407 |
Examples:
|
|
|
1408 |
(I used "-t" in these examples, but it can be "-cc" or "-bcc" as well)
|
|
|
1409 |
|
|
|
1410 |
* Space separated list:
|
|
|
1411 |
-t jane.doe\@yahoo.com "John Doe <john.doe\@gmail.com>"
|
|
|
1412 |
|
|
|
1413 |
* Semi-colon separated list:
|
|
|
1414 |
-t "jane.doe\@yahoo.com; John Doe <john.doe\@gmail.com>"
|
|
|
1415 |
|
|
|
1416 |
* Comma separated list:
|
|
|
1417 |
-t "jane.doe\@yahoo.com, John Doe <john.doe\@gmail.com>"
|
|
|
1418 |
|
|
|
1419 |
* Multiple -t, -cc, or -bcc options:
|
|
|
1420 |
-t "jane.doe\@yahoo.com" -t "John Doe <john.doe\@gmail.com>"

Options related to the email message body:
|
|
|
1440 |
-u SUBJECT
|
|
|
1441 |
-m MESSAGE
|
|
|
1442 |
-o message-file=FILE
|
|
|
1443 |
-o message-content-type=<auto|text|html>
|
|
|
1444 |
-o message-header=EMAIL HEADER
|
|
|
1445 |
-o message-charset=CHARSET
|
|
|
1446 |
-o message-format=raw
|
|
|
1447 |
|
|
|
1448 |
-u SUBJECT
|
|
|
1449 |
This option allows you to specify the subject for your email message.
|
|
|
1450 |
It is not required (anymore) that the subject be quoted, although it
|
|
|
1451 |
is recommended. The subject will be read until an argument starting
|
|
|
1452 |
with a hyphen (-) is found.
|
|
|
1453 |
Examples:
|
|
|
1454 |
-u "Contact information while on vacation"
|
|
|
1455 |
-u New Microsoft vulnerability discovered
|
|
|
1456 |
|
|
|
1457 |
-m MESSAGE
|
|
|
1458 |
This option is one of three methods that allow you to specify the message
|
|
|
1459 |
body for your email. The message may be specified on the command line
|
|
|
1460 |
with this -m option, read from a file with the -o message-file=FILE
|
|
|
1461 |
option, or read from STDIN if neither of these options are present.
|
|
|
1462 |
|
|
|
1463 |
It is not required (anymore) that the message be quoted, although it is
|
|
|
1464 |
recommended. The message will be read until an argument starting with a
|
|
|
1465 |
hyphen (-) is found.
|
|
|
1466 |
Examples:
|
|
|
1467 |
-m "See you in South Beach, Hawaii. -Todd"
|
|
|
1468 |
-m Please ensure that you upgrade your systems right away
|
|
|
1469 |
|
|
|
1470 |
Multi-line message bodies may be specified with the -m option by putting
|
|
|
1471 |
a "\\n" into the message. Example:
|
|
|
1472 |
-m "This is line 1.\\nAnd this is line 2."
|
|
|
1473 |
|
|
|
1474 |
HTML messages are supported, simply begin your message with "<html>" and
|
|
|
1475 |
sendEmail will properly label the mime header so MUAs properly render
|
|
|
1476 |
the message. It is currently not possible without "-o message-format=raw"
|
|
|
1477 |
to send a message with both text and html parts with sendEmail.
|
|
|
1478 |
|
|
|
1479 |
-o message-file=FILE
|
|
|
1480 |
This option is one of three methods that allow you to specify the message
|
|
|
1481 |
body for your email. To use this option simply specify a text file
|
|
|
1482 |
containing the body of your email message. Examples:
|
|
|
1483 |
-o message-file=/root/message.txt
|
|
|
1484 |
-o message-file="C:\\Program Files\\output.txt"
|
|
|
1485 |
|
|
|
1486 |
-o message-content-type=<auto|text|html>
|
|
|
1487 |
This option allows you to specify the content-type of the email. If your
|
|
|
1488 |
email message is an html message but is being displayed as a text message
|
|
|
1489 |
just add "-o message-content-type=html" to the command line to force it
|
|
|
1490 |
to display as an html message. This actually just changes the Content-Type:
|
|
|
1491 |
header. Advanced users will be happy to know that if you specify anything
|
|
|
1492 |
other than the three options listed above it will use that as the vaule
|
|
|
1493 |
for the Content-Type header.
|
|
|
1494 |
|
|
|
1495 |
-o message-header=EMAIL HEADER
|
|
|
1496 |
This option allows you to specify additional email headers to be included.
|
|
|
1497 |
To add more than one message header simply use this option on the command
|
|
|
1498 |
line more than once. If you specify a message header that sendEmail would
|
|
|
1499 |
normally generate the one you specified will be used in it's place.
|
|
|
1500 |
Do not use this unless you know what you are doing!
|
|
|
1501 |
Example:
|
|
|
1502 |
To scare a Microsoft Outlook user you may want to try this:
|
|
|
1503 |
-o message-header="X-Message-Flag: Message contains illegal content"
|
|
|
1504 |
Example:
|
|
|
1505 |
To request a read-receipt try this:
|
|
|
1506 |
-o message-header="Disposition-Notification-To: <user\@domain.com>"
|
|
|
1507 |
Example:
|
|
|
1508 |
To set the message priority try this:
|
|
|
1509 |
-o message-header="X-Priority: 1"
|
|
|
1510 |
Priority reference: 1=highest, 2=high, 3=normal, 4=low, 5=lowest
|
|
|
1511 |
|
|
|
1512 |
-o message-charset=CHARSET
|
|
|
1513 |
This option allows you to specify the character-set for the message body.
|
|
|
1514 |
The default is iso-8859-1.
|
|
|
1515 |
|
|
|
1516 |
-o message-format=raw
|
|
|
1517 |
This option instructs sendEmail to assume the message (specified with -m,
|
|
|
1518 |
read from STDIN, or read from the file specified in -o message-file=FILE)
|
|
|
1519 |
is already a *complete* email message. SendEmail will not generate any
|
|
|
1520 |
headers and will transmit the message as-is to the remote SMTP server.
|
|
|
1521 |
Due to the nature of this option the following command line options will
|
|
|
1522 |
be ignored when this one is used:
|
|
|
1523 |
-u SUBJECT
|
|
|
1524 |
-o message-header=EMAIL HEADER
|
|
|
1525 |
-o message-charset=CHARSET
|
|
|
1526 |
-a ATTACHMENT
|
|
|

|
|
|
1528 |
|
|
|
1529 |
${colorGreen}The Message Body${colorNormal}
|
|
|
1530 |
The email message body may be specified in one of three ways:
|
|
|
1531 |
1) Via the -m MESSAGE command line option.
|
|
|
1532 |
Example:
|
|
|
1533 |
-m "This is the message body"
|
|
|
1534 |
|
|
|
1535 |
2) By putting the message body in a file and using the -o message-file=FILE
|
|
|
1536 |
command line option.
|
|
|
1537 |
Example:
|
|
|
1538 |
-o message-file=/root/message.txt
|
|
|
1539 |
|
|
|
1540 |
3) By piping the message body to sendEmail when nither of the above command
|
|
|
1541 |
line options were specified.
|
|
|
1542 |
Example:
|
|
|
1543 |
grep "ERROR" /var/log/messages | sendEmail -t you\@domain.com ...
|
|
|
1544 |
|
|
|
1545 |
If the message body begins with "<html>" then the message will be treated as
|
|
|
1546 |
an HTML message and the MIME headers will be written so that a HTML capable
|
|
|
1547 |
email client will display the message in it's HTML form.
|
|
|
1548 |
Any of the above methods may be used with the -o message-format=raw option
|
|
|
1549 |
to deliver an already complete email message.

-a ATTACHMENT [ATTACHMENT ...]
|
|
|
1579 |
This option allows you to attach any number of files to your email message.
|
|
|
1580 |
To specify more than one attachment, simply separate each filename with a
|
|
|
1581 |
space. Example: -a file1.txt file2.txt file3.txt
|
|

-o tls=<auto|yes|no>
|
|
|
1600 |
This option allows you to specify if TLS (SSL for SMTP) should be enabled
|
|
|
1601 |
or disabled. The default, auto, will use TLS automatically if your perl
|
|
|
1602 |
installation has the IO::Socket::SSL and Net::SSLeay modules available,
|
|
|
1603 |
and if the remote SMTP server supports TLS. To require TLS for message
|
|
|
1604 |
delivery set this to yes. To disable TLS support set this to no. A debug
|
|
|
1605 |
level of one or higher will reveal details about the status of TLS.
|
|
|
1606 |
|
|
|
1607 |
-o timeout=SECONDS
|
|
|
1608 |
This option sets the timeout value in seconds used for all network reads,
|
|
|
1609 |
writes, and a few other things.
|
|
|
1610 |
|
|
|
1611 |
-o fqdn=FQDN
|
|
|
1612 |
This option sets the Fully Qualified Domain Name used during the initial
|
|
|
1613 |
SMTP greeting. Normally this is automatically detected, but in case you
|
|
|
1614 |
need to manually set it for some reason or get a warning about detection
|
|
|
1615 |
failing, you can use this to override the default.

Options related to networking:

1635 |
-s SERVER[:PORT]
|
|
|
1636 |
-b BINDADDR[:PORT]
|
|
|
1637 |
-o tls=<auto|yes|no>

|
|
|
1639 |
|
|
|
1640 |
-s SERVER[:PORT]
|
|
|
1641 |
This option allows you to specify the SMTP server sendEmail should
|
|
|
1642 |
connect to to deliver your email message to. If this option is not
|
|
|
1643 |
specified sendEmail will try to connect to localhost:25 to deliver
|
|
|
1644 |
the message. THIS IS MOST LIKELY NOT WHAT YOU WANT, AND WILL LIKELY
|
|
|
1645 |
FAIL unless you have a email server (commonly known as an MTA) running
|
|
|
1646 |
on your computer!
|
|
|
1647 |
Typically you will need to specify your company or ISP's email server.
|
|
|
1648 |
For example, if you use CableOne you will need to specify:
|
|
|
1649 |
-s mail.cableone.net
|
|
|
1650 |
If you have your own email server running on port 300 you would
|
|
|
1651 |
probably use an option like this:
|
|
|
1652 |
-s myserver.mydomain.com:300
|
|
|
1653 |
If you're a GMail user try:
|
|
|
1654 |
-s smtp.gmail.com:587 -xu me\@gmail.com -xp PASSWD
|
|
|
1655 |
|
|
|
1656 |
-b BINDADDR[:PORT]
|
|
|
1657 |
This option allows you to specify the local IP address (and optional
|
|
|
1658 |
tcp port number) for sendEmail to bind to when connecting to the remote
|
|
|
1659 |
SMTP server. This useful for people who need to send an email from a
|
|
|
1660 |
specific network interface or source address and are running sendEmail on
|
|
|
1661 |
a firewall or other host with several network interfaces.
|
|
|
1662 |
|
|
|
1663 |
-o tls=<auto|yes|no>
|
|
|
1664 |
This option allows you to specify if TLS (SSL for SMTP) should be enabled
|
|
|
1665 |
or disabled. The default, auto, will use TLS automatically if your perl
|
|
|
1666 |
installation has the IO::Socket::SSL and Net::SSLeay modules available,
|
|
|
1667 |
and if the remote SMTP server supports TLS. To require TLS for message
|
|
|
1668 |
delivery set this to yes. To disable TLS support set this to no. A debug
|
|
|
1669 |
level of one or higher will reveal details about the status of TLS.
|
|
|
1670 |
|
|
|
1671 |
-o timeout=SECONDS
|
|
|
1672 |
This option sets the timeout value in seconds used for all network reads,
|
|
|
1673 |
writes, and a few other things.

Options related to output:

1693 |
-l LOGFILE
|
|
|
1694 |
-v
|
|
|
1695 |
-q
|
|
|
1696 |
|
|
|
1697 |
-l LOGFILE
|
|
|
1698 |
This option allows you to specify a log file to append to. Every message
|
|
|
1699 |
that is displayed to STDOUT is also written to the log file. This may be
|
|
|
1700 |
used in conjunction with -q and -v.
|
|
|
1701 |
|
|
|
1702 |
-q
|
|
|
1703 |
This option tells sendEmail to disable printing to STDOUT. In other
|
|
|
1704 |
words nothing will be printed to the console. This does not affect the
|
|
|
1705 |
behavior of the -l or -v options.
|
|
|
1706 |
|
|
|
1707 |
-v
|
|
|
1708 |
This option allows you to increase the debug level of sendEmail. You may
|
|
|
1709 |
either use this option more than once, or specify more than one v at a
|
|
|
1710 |
time to obtain a debug level higher than one. Examples:
|
|
|
1711 |
Specifies a debug level of 1: -v
|
|
|
1712 |
Specifies a debug level of 2: -vv
|
|
|
1713 |
Specifies a debug level of 2: -v -v
|
|
|
1714 |
A debug level of one is recommended when doing any sort of debugging.
|
|
|
1715 |
At that level you will see the entire SMTP transaction (except the
|
|
|
1716 |
body of the email message), and hints will be displayed for most
|
|
|
1717 |
warnings and errors. The highest debug level is three.
