SENDMAIL sends an email message from TCC via SMTP. The text of the message can be entered either on the command line or read from a text file. SENDMAIL also supports SMTP over SSL. If you don't specify any arguments, SENDMAIL will display its command dialog.


Before you can use SENDMAIL, you must either set the SMTP configuration options, or have a default account in the registry. Depending on your system configuration, you may also need to start an Internet connection before you use SENDMAIL.


A SENDMAIL message has three required parts: an address, a subject, and message. Optionally it may also have attachments.


1. The address field contains one or more standard Internet email addresses:


sendmail [email protected] ...


If address contains white space, the entire address field must be surrounded by quotes. You can specify multiple destinations by separating the addresses with commas and enclosing the entire string in quotes (all addresses will appear in the "To:" header sent to all recipients). You can add CC (copy) addresses by prefacing the desired target(s) with cc:; and BCC (blind copy) addresses by prefacing the desired target(s) with bcc:. For example:


sendmail "[email protected] bcc:[email protected]" Test Hello!


will send the text Hello! with subject Test to [email protected] with a blind copy to [email protected].


2. The subject will appear as the subject line in the message. If it contains white space, it must be surrounded by quotes.


3. The message may either be entered on the command line, or it may be placed in a text file. To tell SENDMAIL to send the contents of a file as the message text, use @ sign, followed by the filename. You can use the same approach to send the text content of the clipboard (@CLIP:) or the console (@CON:):


sendmail [email protected] Party @c:\messages\invitation.txt

sendmail [email protected] Party @clip:

type myfile.txt | sendmail [email protected] Party @con:




/=Display the SENDMAIL command dialog to help you set the command line options. The /= option can be anywhere on the line; additional options will set the appropriate fields in the command dialog.


/A fileAttach file to the email message. The /A switch and the name of the file to attach must appear before address. Any file name that contains spaces or special characters must be quoted. You can send multiple files by repeating the /A switch for each additional file to send. For example:


sendmail /a file1 /a "d:\path\My file2" [email protected] ...


/Command="command"Send additional commands directly to the server. You can specify multiple /Command="..." arguments.


/DRequest Delivery Notification.


/Date="date"Create a Date SMTP header and attach it to the message. (If this option is not set, the default SENDHTML behavior is to create a Date SMTP header reflecting the current date and time when the message is sent.) RFC 822 contains detailed date format specifications. An example of a valid date is "Mon, 1 May 20:15:00 EST".


/ESet the "reply to" address in the message header.


/HSet a custom header. The header will be appended to the message headers created from "to", "from", "subject", etc. The headers must of the format "header: value" as specified in RFC 822. You can specify multiple headers with multiple /H arguments. For example, to send HTML mail:


sendmail /h"Content-Type: text/html" ...


/InSet the Importance where n is:


2Normal (default)


/IPv6Use IPv6 instead of IPv4.


/MUse CRAM-MD5 authentication.


/PnSet the Priority where n is:


0Unspecified (default)
3Non Urgent


/R(Read receipt) : Send a read receipt.


/SnSet the message sensitivity. The values are:




/SMTPOverrides the default SMTP server (as set in the registry) to use when sending mail.


/SSL=nType of SSL negotiation. The values are:


0Automatic (default if no n value is specified). If the remote port is set to the standard plaintext port, SENDMAIL will use Explicit mode. In all other cases, SSL negotiation will be implicit.
1Implicit - SSL negotiation will start immediately after the connection is established.
2Explicit - SENDMAIL will first connect in plaintext, and then explicitly start SSL negotiation.
3No SSL negotiation or security. (This is the default if /SSL is not specified.)


/USEROverrides the default email account (as set in the registry) to use when sending mail.


/VShow all the interaction with the server, except the message header and message body text.


/XSend EHLO instead of HELO.
