To send mail to multiple recipients without including each address in a recipient (To:/Cc:/Bcc:) header field, create a text file in the 'Lists' subfolder of the 'Configuration' folder. The text file should contain a list of valid e-mail address entries (see 'Editing an outgoing message for a description of valid addresses). Each address must be on a line by itself.
Now start a new message, and on the 'To:' line, type an adress consisting of the name of the mailing list file, followed by '@rexxmail'.
For example, if the name of the mailing list file in the 'Lists' folder is 'maillist', type 'maillist@rexxmail'.
Now complete, save, and send the message like you would any other outgoing message. RexxMail will send it to each of the recipients listed in the 'maillist' file.
