Notes

Connecting to a host

The host specified in the -h switch should be the DNS Name or IP Address of your SMTP server. In many cases that will be the server provided by your ISP- for example:

	CSSmtp -hmy.mail.server

Specifying the originator and subject

The -o switch should specify the email address, and optionally the name, of the originator (usually yourself) - for example:

	CSSmtp -hmy.mail.server -o"Fred Bloggs <fred@bloggs.co.uk>"

Remember that Windows 95 and NT require that you put quotes around command line arguments which include spaces.

See the notes below for information on how to specify names and addresses.

The -R switch allows you to specify a different reply-to address.

The -s switch provides the subject of the message - for example:

	CSSmtp -hmy.mail.server -s"CSSMTP is a great program"

Watch those spaces again!

Specifying the recipients of the message

The -r, -c and -C switches specify the list of normal, CC and BCC recipients for the message. Each recipient address should be specified in the same format as the originator address and the addresses in the list should be separated with commas.

Specifying the body of the message

The -f switch should list a set of files which go to make up the body of the message.

The full path of each file should be specified and the files in the list should be separated with commas. By default the files will be included in the body of the message, if you wish the file to be a message attachment you should precede the name of the file with a plus sign:

	CSSmtp -fc:\docs\file1.txt,c:\docs\file2.txt,+c:\docs\file3.txt

The first two files are included in the body of the message, the third is included as an attachment.

You can specify stdin as a source of message text by including an empty filename in the list:

	dir | CSSmtp -fc:\docs\file1.txt,,+c:\docs\file3.txt

Puts file1.txt into the body of the message, then includes a directory listing, before attaching file3.txt to the message.

CSSMTP will automatically determine the correct encoding scheme to use for each file; either 7bit for normal text, quoted-printable for text including extended characters or base64 for binary files.

By default CSSMTP will use Mime Version 1.0 multipart/mixed content type messages to send the message. In some cases you may need to use UUEncoded messages for compatibility with legacy mail clients. The -u switch disables MIME Version 1.0 support and causes CSSMTP to send files as normal text, uuencoding them when necessary. The -U switch results in all files being UUEncoded, regardless of their content. If either the -u or -U switch is used then a '+' preceding any filename arguments will be ignored.

ESMTP authentication

CSSMTP can establish an authenticated connection with an ESMTP server using either the PLAIN or LOGIN authentication methods.

The -n and -p switches specificy the ESMTP credentials. If either of these switches is included in the command line an ESMPT connection will be attempted with the given credentials:

	CSSmtp -hmy.mail.server -nEKrabappel -pseymour ... 

The default ESMTP authentication method is PLAIN; to specify LOGIN authentication you can use the -m switch:

	CSSmtp -hmy.mail.server -mLOGIN ... 

MIME Content-type charset value

The -l switch may be used to specify a specific value for the charset part of the MIME Content-type field, this allows language dependent character sets to be used - for example:

	CSSmtp -hmy.mail.server -lISO-8859-2

Uses the ISO-8859-2 character set.

If no value is specified the default, us-ascii, is used.

Specifying names and email addresses

Full name and address - Fred Bloggs<Fred@bloggs.com>

Just the email address - <Fred@bloggs.com> or simply Fred@bloggs.com

Exit ('ERRORLEVEL') codes
